AFPR Problems
 

so i put a Aeromotive fpr in last night and got my 880cc injectors in and got everything sqaured away then set the pressure and cant get it to start now, i have a walbro 255 aslo in, it will fire once sound like its gonna go and doesnt , i dont know why ne one help?

Re: AFPR Problems
 

Do you get pressure on the gauge on the FPR? (Did you put one in?)
Have you primed the system? Odds are when you put in the fpr the rail got drained and there is not fuel in the system.
Did you bump/disconnect anything else while you installed the fpr?

Re: AFPR Problems
 

Do you know what a barb fitting is?

Re: AFPR Problems
 

yeah it was getting pressure on the gauge,and im positive i have everything hooked up right i double triple checked...If I get pressure should i still have to prime it?

Re: AFPR Problems
 

yes, only because you've drained the system when you pulled the stock fpr off the rail. Double, triple checked? Does that mean you checked like 6 times? lol

-A. Swift

Re: AFPR Problems
 

How about this..... Did you use anything to TUNE YOUR CAR for those sweet 880's you got? Did the car ever run w/ the new injectors and FPR? What's your fuel pressure? How are your lines hooked up? What did you "square away" when you put it all in? Usually information like this is good when you want other people to tell you what's wrong w/ your car. Despite how many times you've double, and triple checked, you obviously are missing something and everything isn't "right"

Re: AFPR Problems
 

hell yeah,lol so prime it then see what happens OK got ya.

Re: AFPR Problems
 

well the only thing i can think of is somthing to tune it with but it should still atleast start, and the fuel pressure is at 43psi, and as for running it ran for like 30seconds with the new stuff in at a rough idle but i expected that, then it quit and shut down and now wont start, no codes came up and no check engine lights either, and the only reason im asking for help is because ive not used these fuel upgrades before and ive been working on this for awile.

Re: AFPR Problems
 

what is the best to use for tuning this? that fuel setup with a t3/t4.

Re: AFPR Problems
 

Your car isn't going to run if you don't have anything to control your TWICE THAN STOCK SIZED injectors. I'm gonna GUESS that your fuel pressure was low enough before you set it to BARELY run the car.

Re: AFPR Problems
 

When you set it at 43psi, did you have the vacuum port disconnected on it? I'm assuming this is a 2g since you have it set at 43psi. You should have the vacuum line disconnected when setting it to 43. Then when you plug it back in, the pressure should go down some since you are in a state of vacuum.

And are you saying you have nothing to tune with? You just threw 880's in and figured it'll be just fine without any changes?

Re: AFPR Problems
 

I know it needs somthin to be tuned with that would be why i asked what is the best for this, did you not read the last post, And yes this is the first time ive put somthing like this in so fuckin chill, you obviously didnt wake up one morning and know how to install a whole fuckin fuel system in one night we all learn some where, hence why im asking, I would appreciate if you would just tell me what im doin wrong instead of giving me shit for not doin it right , not trying to be a prick but I dont like being talked down to just because I dont understand somthing.

Re: AFPR Problems
 

When I started typing, the latest post was post #8, so no I did not read the previous posts.

But you know what, screw you. Figure the shit out on your own. I wasn't trying to be a dick. I was telling you how to set your base fuel pressure correctly because that is important, and asked if you were using nothing to tune with because it hadn't been made clear by post #8 which was the latest post when I started my reply. I'm perfectly chill. If you think my responce was harsh, well then you need to rinse the sand out of your vagina, because that was hardly harsh.

Re: AFPR Problems
 

Christ just tell what is a good tuning tool so i can buy it!and drink beer:beer: and put the fuckin thing in, im a lil egdey sorry for snappin, been doin this for like 3 weeks straight.

Re: AFPR Problems
 

At the risk of being insulted, I'll offer my opinion.

If you didn't know you needed a tuning device for those injectors you will not have the knowledge required to use the tuning devices needed for them. Perhaps if they were small enough to use a SAFC.

I'd suggest a keydriver chip + SAFC. Then again, someone with more tuning experience will probably chime in. Perhaps you could use a more complex setup in a basic mode...

I dunno.


*BTW* You have an extra letter in your signature.

Re: AFPR Problems
 

Put in your stock injectors if you want to drive it. When your computer pulses fuel thinking it has 450's and you actually have 880's, you're dumping fuel like crazy. If you keep dicking with it as is, you'll wash your cylinders down and need a ring job. :rtfm:

Re: AFPR Problems
 

well i just got done putting the 450's back in and guess what, not runnin still so its somethin with the fuckin fpr not the injectors.

Re: AFPR Problems
 

Ok, put the 880's back in then ;)

how are the lines routed on your FPR? you need to check everything that I listed above again. Installing a FRP isn't this complicated, or hard. Unless your swifty

Re: AFPR Problems
 

You are being talked down to because you jumped in way over your head and don't know what you are doing. Most people do some research before they start buying random parts.

I am with Steve, put your 450's back in and run the car. What year is the car? If it is a 2g, get DSMlink. A 1g is a bit more difficult, a Eprom ECU and SAFC is probably the best bet though. What turbo are you running where you need 880's? What other mods do you have?

Re: AFPR Problems
 

If it's still not running, then perhaps there's a possibility that you've already flooded the motor?

Re: AFPR Problems
 

im not jumping in over my head this the only thing that hasnt worked, before i put the new fpr in it ran perfect too it just hit cut at like 8 psi because of the new turbo, tis why i wanted new fuel supply to run more boost, but here is every mod ive ever done,
Mitsu, Eclipse, GSX, 1997, 4g63t

T3/T4 turbonetics 60-1
Tial waste gate
Turbosmart boost controller
Tubular header,3" exhaust from the down pipe back.
ARP headstuds brand new head gasket.
injen intake, Big FMIC, HKS ssq bov
NGK wires w/ Iridium plugs
ACT flywheel and clutch
Reman tranny
B&M short shifter
new timing belt
Underdrive pully
new alternator and battery.
255lph walbro fuel pump
Aeromotive FPR
The 880cc injectors
brand new fluidine radiator samco hoses w/ slimline fans

Leak down tested and compression tested, I think that I did some more I just dont really remember off the top of my head, the only reason I havent got a tuning tool yet is because I dont really wanna deal with this mess of fuckin wires, the guy before had hacked like all the wires and me not being good with wires this sux, plus U know that plug where youd hook up like a OBD II yah that doesnt work this thing is like a wiring nightmare I cant even figure out how to hook up my a/f ratio gauge its so bad.:confused: IDK and I thought about dsm link but what happens if it still dont start or i cant get it hooked up that 500 bux gone wasted, upon all the other money already spent.

Re: AFPR Problems
 

You should not be hitting fuel cut at 8 psi, no matter what turbo you are on.

Fuel supply has nothing to do with fuel cut.

Like has already been said, you need to do some research before sticking parts on the car. Some form of tuning device should have been on your list before half of the other parts.

Re: AFPR Problems
 

are you high yah im sure that my stock fuel components can support a turbo double the size of the old one makes so much sence to me now wow so I can run a big ass semi truck turbo and never need more fuel than stock to support it and get more boost wow thats amazing peer genius go fuck ur mother:loser: , maybe ill also try running 900hp without doin shit to my internals next sound good and would ya help me fill my halogen fluid too, for christ sake and ive researched this engine so that i know it better than the back of my hand btw im not some dumbass 16yr old kid workin on my honda im damn near 20 and have been around car engines my whole life
:offtopic:
are you stupid you sound like politicians beating around my questions, I already have the shit in, everthing is in, why would you telling me that im in over my head and that other BS help me im not gonna take it all out am I, you dont tell a guy almost done buildin a fence that its not painted so take all down and paint it, you paint it where it stands, Im a lil ahead of the game I KNOW THIS, I ALSO already know I NEED A TUNING DEVICE BUT THE CAR DOES NOT START SO WHAT GOOD WOULD IT DO. I ORIGINALLY ASKED WHAT DID I SAY "WHY DOESNT IT START" THE TITLE AFPR PROBLEMS MEANING PROBLEMS WITH THAT, NOT WITH THE INJECTORS CUZ THE OLD ONES ARE IN NOW AND IT HAS THE SAME PROBLEM WHICH WOULD MEAN NO PURPOSE FOR A TUNING TOOL NOW WOULDNT IT, It doesnt matter close this god damn thread...this is pissin me off more than the car.:madashell:

Re: AFPR Problems
 

Read carefully
1.) 880's will not run your engine without something to tune them with. SAFC, dsmlink, aem, whatever....
2.) YES, you have more problems than just the injectors being uncontrolled
3.) I asked you before how you had your FPR routed to try and help you, but you keep being an asshat and wondering why people are giving you shit instead of trying to fix your problem
4.) From reading your posts, and what you :think: you know about your car, it's really obvious that you don't know as much as you :think: you do
5.) You have 13 posts, most of which are from this thread. No one here knows you. At all. You don't make a good first impression, or make anyone wanna help you by bashing the site OG's, and acting like you know more than everyone here

Re: AFPR Problems
 

here is the wiring mess im dealin with. this was like this when i got it.

Re: AFPR Problems
 

Keep the 450's in and check for spark, constant fuel pressure while cranking, and make sure the injectors are actually firing

Re: AFPR Problems
 

kk ill keep ya posted if that works.

Re: AFPR Problems
 

Did you pull the plugs out and make sure they weren't soaking with fuel?

I would switch to some NGK copper plugs too. Also get that underdrive pulley off there, unless it is an real dampner, instead of just a piece of billet.

As others said, fuel cut has nothing to do with fuel supply, running out of fuel, being too rich or too lean. Yes, you do need a bigger fuel system for your setup, but without doing something else, putting in bigger stuff won't get rid of fuel cut. Fuel cut happens when the ECU sees too much airflow, the stock ECU thinks the wastegate has failed causing the turbo to overboost and it shuts fuel off. You can mod the facotry ECU(chip or DSMLink), get a different ECU, or try to trick the ECU by lowering the airflow reported to it(SAFC).

Put the 450s in, change the plugs, maybe even remove the AFPR setup and see if it will start or has fuel and spark. Make sure you don't have a big boost/vacuum leak somewhere too.

Re: AFPR Problems
 

The fuel line goes from the fuel rail to the AFPR and then from the AFPR to the rubber return line right? It's a little hard to see in the pics.

Is there a little air filter on your intake pipe right after the MAS? That would cause some major air metering problems.

Re: AFPR Problems
 

I didn't notice that. This thread just gets better and better!



Anyway, glad to see you're finally taking advice. You certainly haven't made a friend out of me, but it looks like there are still people willing to help you out.

Re: AFPR Problems
 

yup, and the filter is blocked just was seeing what it looked like lol.. it dont look good either was bored and found it in the trunk.

Re: AFPR Problems
 

yeah thats all good and great but i dont think in that mess of wiring i will be able to figure how to get a safc or dsm link hooked up ya know unless im givin like an really specific instructions and even then i dont think there is one single wire or harness where it should be, if you have like a picture of it hooked up in a car it would help me alot, i learn more from pics and hands on then words.

Re: AFPR Problems
 

dsm link is a chip for the ecu you do not need to wire it in. Just have to have a eprom and have some one socket it for you. the wiring does not look that bad I have seen and fixed worse than this. The worst was a kid on here that put in a safc and used duck tape on the wires to hold them to the ecu wiring after he striped the wires and he could not figure out why it did not work right.

Re: AFPR Problems
 

I have a 750cc chip w/ timing topping at 18 degrees and an SAFC1 if you want them for $150. :)

Re: AFPR Problems
 

That is his air meter by pass filter, it needs to be bigger to avoid fuel cut though, or his flamitation valve is sticking.

I would get somthing to tune the car as said, new plugs, and pay someone to dyno tune the car.

He doesn't have to do that, the car won't ever run :hah:
