Well i finally finished my turbo kit Fri night so i decided to drive to track,well didnt make it home so maybe you guys can help me firgure it out..

When i got on the interstate the car start hesitating really bad,i pushed the gas and nothing,so i figure im out of gas so my freind went to go get some for me! We put the gas in the car started but was smoking black.So i know it was running rich,so i drove to next exit and left the car, the next day i figured its eighter the resistor box or 440 Injectors.So we pulled it all out and put my stock ones back in and took resistor box out as well... The car started fine and Ideled fine, so i start my 40 mile drive home, get about 20 miles and the car does the samething.
So i changed fuel pumps,changed the main relay and nothing..Its reading no fuel presure on my gauge... We pulled the injectors and there like driping not srpaying or anything....
So what you guys think it can be???
I have a gsr motor, drag kit on the car, and i didnt boost at all because the wastegate spring is sticking open..So i dont think the motor is blown, I also checked all the fuses, timing is on mark so it isnt timming, im getting spark, when i pulled the pulgs they were black becasue the car was running rich the night before!!

PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!!

Obd1 or 2? Did you buy obd2 injector clips? You mayhave wired your injectors wrong.

Ok you say it's got no fuel pressure....can you hear the pump come on?

HYBRID_H@TCH

make sure your fpr didnt somehow stick open letting all the fuel pressure by.also check your fuel filter to make sure its not 100% clogged

Its Obd 1 and no i didnt have to get clips, also the fuel pump does kick on and i do hear it run.. It does have a aftermarket Fpr...
My gauge is on the fuel filter..
so waht would you guys try doing???

GaRn

maybe your injectors seized from to much of a work cycle? doubt it though because of 440's lol.

I dont think its injectors,becasue when i put my stock ones on it still did the samething, Keep in mind my car is turboed but i was running 0 boost becasue of wastegate!!!

I wired the injectors wrong (dsm 450's) and the fuse to the ECU kept blowing. That resulted in no fuel pressure at all and the engine wouldn't start.

Checked the fuses they were all fine!!!!! Even when we took the resistor box and the 440 the car should have ran fine on stock setting but nothing.. i guess my problem is no fuel presure, so what would you guys check next???

ahobbs

i would say put the stock regulator back on and watch it drive normal.

If you have no fuel pressure, it's either the fuel pump or injectors, or regulator.

Well we pulled the injectors to see if they were spraying and they were dripping not spraying!!!!

Pull the pump out and make sure the rubber hose on top of it doesn't have a hole in it. Mine bursted last week and I had zero fuel pressure. Hope you know what hose I'm talking about.

What cat. converter are you running? Kinda sounds like a clogged converter.

Nextelbuddy

hes not running a CAT.

IloveNewt

take a look at ur map sensor. Maybe wiring...

havok hybrid

sounds to me like the Map Vacuum came off .. Do you get a check engine light?

Nextelbuddy

using stok MAP sensor. its OBD 1 so the MAP is bolted to the throttlebody. no hes not getting any CEL's thats what is boggling us. no codes so we dont know what the problem is. we even swapped ecu's with a known good one and still same results. i guess this is where OBD 2 would come in handy because the ECU wold probably pinpoint the problem a little better due to slightly more snesors. i dunno just a thought.

Fixed.. it was the fuel filter...............

Jeff33S

I was about to say check the filter because if you heard the pump priming you should still have pressure to the rail.

If you got no fuel pressure injectors wouldnt due much good anyways so that would mean you problem would lie somewhere between the pump and the rail.

Good to hear you got it taken care of.
