View Full Version : Need a new hpfp
DaveIrwin24
12-06-2012, 03:47 PM
On Monday out of nowhere my car would hit a wall in 3rd gear, boot would cut off and it would stutter. Even in first gear it was doing that.
When I drove Tuesday, Wednesday car was fine and had no problem hitting full boost.
So I dropped it off at the dealership today and they called telling me the issue was the hpfp and that I need a new one. Thank god it's under warranty.
They told me the current one most likely was defective.
The only mods I have are a cai, bpv,and CBE.. I know anything more then thy I would have to upgrade the hpfp.
Car only has 23,000km
Just thought it was strange

That's very weird, my 2012 is at the same Km's and my pump is still good... I hope lol.

Given the difference in fuelling logic between first and second generation Speed models, you arguably should have already had a HPFP installed.

Actually you may want to consider upgrading the hpfp even with those simple mods. The gen2 speed 3's it was recommended that you upgrade the hpfp before installing a CAI.

Upgraded HPFP is recommended but not "needed" unless you are one of the lucky few who's fuel pump goes poopy, but I do understand where everyone is coming from with fueling issues as we all know about the zoom zoom boom boom.
You have an AP or dash hawk? (you should get something to watch your pressure cuz SFW's comment about the CAI)
Edgeautosports has deals on the accessport and autotech internals combos if you don't have either already.

What a great time to see if they will give you free labour on the purchase of a HPFP even though the install is pretty basic, it's cold out. I'd ask if you could bring in your own pump, dunno if it would fly but probably couldn't hurt. I'm surprised they are giving you warranty as well
DaveIrwin24
12-06-2012, 05:47 PM
Yeah that would be a great idea, everyone is pretty easy going at the dealership.
Too bad I gotta wait till spring for any more goodies on the car, I guess house repairs are more important :( lol
I'm surprised they covered it under warranty, I told the service advisor my mods and if they were the reason and he said not at all.. Lol

Too bad your dealership is out in Nova Scotia, as they seem to be really understanding about mods and just in general.

What's a good site to get a reasonable priced hpfp?

Check with Alphamotorsports on TM3 or EdgeAutosport on MSF/their own site.
Full replacement or internals they should be able to help you.

Thanks for the links, I thought a hpfp was $600 +.. Those prices on the links are reasonable!
Well for now ill get them to replace with a OEM pump and if I run into any issues before spring ill know where to buy.
It's kinda ridiculous how the hpfp needs to be upgraded to do anything.. You think they woulda changed that on the 2nd gen hahha I'm sure that has been ranted about a number of times!

Just to clarify, the links I posted are for hpfp internals... not a complete full replacement pump (those cost $600+). Which one you choose is an open debate and entirely up to you to decide :)

from what i know is it has a different tune vs the first gen which you can almost put any mod in and have it be ok. im sure someone knows the specifics but i would think it runs pretty close to its max as it is where the first gen may not. but who knows.

Speeds are not the only performance-oriented cars with fuel pump issues. E92 335s apparently have similar issues once you start making more power than stock.

My buddy just picked one up and was debating between getting a JB4 or a HPFP...luckily I steered him in the direction of the fuel pump.
I've already got the plan worked out for when I pick up my Genpu
RMM > BPV > AP > HPFP > SRI+TIH > DP. Probably the safest possible mod path (except for starting with AP + HPFP, of course).

In the Gen2 the if the fuel pressure drops below 1600psi then the injector pulse width increases causing the car to over fuel and robs power and thus saves the engine, where the gen1 it would lean out hence the Zoom Zoom Ka Boom.
Now the variances with manufacturing of the HPFP has actual some Gen2's with just as much as an intake installed cause fuel pressure to drop below 1600psi at WOT and cause power loss. You will never blow an engine in a Gen2 just hit a wall with the HPFP.
I had a MazdaSpeed CAI installed on my Gen2 and on my logs I would hit 1693psi initially but as speed and rpm increased it would stabilize out at 1740-1750psi at WOT pulls in my logs. Every car is unique and you must be able to monitor fuel pressure but with a catback exhaust your fueling demands might be more than just an intake. Log and post with new HPFP.

They have a recal on the HPFP's also on the injectors
As for everyone wondering why he got warranty on the pump, dealer has to prove the pump failed because of mods. Pump is mechanical for the most part and therefor cannot be affected by Anything else.
As for replacement pumps, spend the money and get the CP-E one. Up front you have to fork over about 1000$. Once you send your old pump back they return 400$ to you. To bring I over the border it's about 80$ in taxes. Just make sure you choose USPS

Is it a recall so everyone gets new pump and injectors or is it just if you have issue and you have warranty they replace items, also if you have bad injector do they replace all 4 or try to figure out which is the bad one? What years are affected?

I wouldn't say "can't" but the fueling logic is different in that when fuel pressure drops below 1600psi (or so) it just dumps fuel into the engine further lowering pressure but also making the engine go really rich which prevents detonation which is the cause of zoom zoom boom. The first gen would just let the pressure continue to fall and consequently the AFR's would continue to rise until...boom.

Whoa, this is the first I've heard of this. You CAN'T blow the Gen2 engine? This goes against everything I've read regarding the HPFP situation.
Nope you cannot blow the engine with the fuel logic that is present, Hence the first mod needed to be done before any combination mods is the HPFP. You will not blow a Gen2 engine from leaning out with this logic that's 100%, you will hit a wall once your fuel pressure drops below 1600psi and then logic increases pulse width and you get more fuel from injectors just being at max pulse width and you get robbed of any power due to this logic! Just read up on Cobb tuning website it is explained in detail there!
Now if there is another mechanical issue with the car yes you can blow the engine, like no oil, low oil viscosity, VVT chain stretches and you jump some teeth and valve hang open etc... But to blow engine due to leaning out like a gen 1 that's modded like a MO FO!! without a pump upgrade never! Now this would be a good question to ask if you have a Cobb AP if those tunes take away this fueling logic? I doubt it, but none the less would be a good question.
P.S read the FYI in the Cobb section or their forums you will find the truth, reading other forums is mixed with fact & fiction!

So the question is was the member on stock tune? If the aftermarket tune takes away this fueling logic or this safety feature then monitoring fuel pressure is critical but then you would have to get a HPFP to ensure you do not blow your engine while using an aftermarket tune.
A stock car, with a stock tune or with an CAI,TIP, and a properly functioning stock HPFP will never blow an engine you might hit a wall when fuel pressure dips bellow 1600psi if you put CBE,DP,TMI/FMI but you car will not blow up due to leaning out on a stock tune you will just keep hitting PCM limitations!

PROOF this Gen2 owner on a stock tune had fuel pressure drop below 1600psi he did not lean out and damage his engine but hit PCM generated limitation, he parked his car then drove it to the dealer, new pump and engine is fine. I would believe that the CBE exhaust paired up with his other mods and a inferior pump being pushed to its limits was the cause for failure. There is a variance from pump to pump as to what mods will show the stock HPFP weakness.

So the dealership ordered the hpfp last Friday , still waiting for them to call me to tell me they have it in and they'll install it. I've been driving my car around, everything seems fine, turbo hasn't been surging or losing psi while wot.
I'm assuming the same thing will happen with the new hpfp they are gonna install as the original one I have now because of my mods?
Or will this hpfp be a better functioning one that can withstand the mods I have now.
I'm hoping the pump was defective and the new one will be alright until I can upgrade in the spring.

12-13-2012, 10:05 AM
It will be the same as the stock HPFP, they prolly had a defective batch of HPFP so they are replacing them with new ones that aren't from the same manufacturing date. You should be fine but I would jump on some upgraded internals or a complete HPFP upgrade when they go on sale for boxing day or any other sale.

you might of had a really weak pump? hopefully you get lucky and have no further issues if there was a problem as everyone says with the HPFP from a specific date. If this is all the mods you are going to do I hope the new pump will flow enough to keep you happy! Buy a monitoring device or an AP to watch and log your runs with new fuel pump.
Good Luck

It comes down to the car itself. For example a friend of mine with a 2010 speed (same as mine) had an intake prior to the pump and his car drove fine in any condition. My car had the same intake and in 3rd gear above 4000rpms it would stutter like crazy prior to the pump. Just take it easy until the internals are in

cars are not mysterious, you just need something to allow you to tune the car properly.
Unless you're planning on getting a Cobb Accessport soon, I would suggest putting the stock intake back on.

The car may be a production line car however every car is differen't. How the car is driven and broken in will also change the cars charecteristics drastically.

If the car was having fueling issues with the stock pump and you swapped in a stock pump and still have fueling issues. I suggest getting that car back to stock because if you blow something, the dealer has surely made a record that the car was not stock. No mystery here. You are feeding the car more air and with the exhaust, allowing it to escape faster. All things equal, the car simply does not know how to compensate. The MAF can make some adjustments but you're asking a lot from it and if it can not supply the fuel needed but you still keep feeding it the air, there is no mystery to what will happen.
An AP although not the cheapest mod to buy is THE BEST to purchase first. Until you have something to show and log what is going on, you really have no clue. In a lot of cases, neither does the car.
Personally I would stock that car before hitting boost again. Motors aren't cheap. By comparison an AP is. Much easier to install as well.
You'll also have a hard time finding a MS3 motor at the junkyard which means the only other solution if you window the block is to buy from the dealer or buy a new block and throw your own goodies in.
Either or, you're looking at 10 times the cost at a minimum of the price of an AP.
DaveIrwin24
12-26-2012, 12:18 AM
The car only had 15km off the lot, the only time I have ever pushed the car was on a lapping day at the track on the summer. Normally I take it pretty easy on the car.
It's apparent it's the mods like you guys are saying. I wanna take the safest path from now on out without damaging the engine anymore.
I guess ill just explain the situation to the dealership when it opens, and take off the intake and CBE if necessary.
Order ap and internals looking forward before I think of putting anymore mods on.
Thanks for the input guys

Something that everyone neglects to me took is that if your pack if fuel weakens your rods, down the line, even after you have put a new pump in or swapped the internals, there is no reset, if the metal is in any weakened, it can not repair itself, they are not organic creatures.
Whatever damage is done or is being done can only shorten the life span of your motor and 2 years from now, if something goes wrong and you window your block because the rods were weak and snap, it's not a design fault. These motors car live long healthy lives, if maintained and treated properly.
We all must understand this and we all must understand that any modification to the engine to increase power or efficiency is going to shorten the lifespan of that motor.
This is not directed at you but to everyone modifying their car.
We also forget that time 5 years ago when we let the engine oil dip low or go too long between change intervals. Then when we spin a bearing, all of a sudden, we scream design flaw. We are all guilty of it but I know Fobio has preached this dozens of times but here's one more; every time one of these engines blows prematurely, the value of our cars decreases. Every time someone safely makes say 400hp, our resale value increases. People buying used cars do their research and if/when I am ever ready to sell my Speed 3, I would like to get the most possible from it.
Sorry if it came off as harsh but it's for everyone, and done properly, these cars can be modified for good gains or great fuel economy. The benefit we all have now is that most of us aren't breaking ground with this platform. The mistakes have been made for us. We can safely modify these cars by following a few key steps. If you are not prepared to constantly log and keep your eyes on your access port, I don't suggest modding much more than you have until you take it to a pro to have it tuned.

Sounds like when they said I needed a new starter connector and that they replaced it but the part on there was still old and had not been moved.
LOL
Happened when my car tossed 15-20 or so codes and what was actually wrong was the immobilizer lost the programming
Ask to see the old part, maybe it's legit as the steering sensor has a relation to boost
I still highly suggest a Cobb Access Port or other monitoring/tuning device

Go get a pump and your problems will disappear as to me this sounds more like the dealer is firing parts at it because they have no clue what's wrong with it. The maf sensor would cause all kinds of driving malfunctions but i highly doubt a hpfp fueling issue as it is a mechanical part. The steering angle sensor makes no sense to me either, as comparing them to cars at work with a turbo I have never seen it be affected by the steering angle. Now the injectors? Come on to me this sounds like a parts cannon car

Not sure where to ask this and did not want to create another thread with the same title. Currently my car runs fine with no problems at all and I rarely if ever drive it hard. I might hit 5000RPM once in a while.
Installed: AEM Cold air Intake with AEM Bypass valve - I simply did this for the unique sound it creates and the small performance enhancement it may or may not have. I would like to add a cat back exhaust at some point in the near future.
Should I be looking to replace my fuel pump at time of cat back install? Should I have it installed now? Do you think I require one?
Based on comments above, it seems as though the best thing to do is go back to stock. If I start to experience serious problems I will go back to stock. However, until then I would like to upgrade the air flow and do it correctly based on others experience.
Will I require the AP in order to make all this work as its intended?

On the 2nd gen a fuel pump/internals upgrade should be considered even before an intake. Since you already have an intake, I would next upgrade internals or buy a fuel pump, then if you want a CBE go that route. However, you will see more performance from the car, by opting for an AP before the CBE, and then altering the stock tune.

S.F.W - Thank you very much, I will definitely follow whatever advice you throw my way. After the CBE upgrade I am done with engine upgrades so I want to do this right the first time.
This might be the best noob question ever!!
I understand Fuel Pump but I am lost when you mention "internals". I am likely thinking too much of nothing but what parts exactly are you referring to? Or in other words, could someone dumb this down enough so I know exactly what to buy haha.
Sorry guys, just not sure where else to ask these total noob questions. I can only read so much before I get to confused

Internals are just what is inside the high pressure fuel pump, you upgrade the internals or upgrade the entire pump but both essentially do the same thing. It just replaces the cyclinder inside the pump to create more pressure if needed.

IMO just buy the CP-E pump and bolt it on.

Yup and it's worth every penny, comes tested and ready to bolt on, also CP-E backs it up with a warranty.
