You said you checked fuel stuff, but is fuel actually flowing?

do you actually have fuel in the car. Not trying to sound like an ass but that seems to be the problem no fuel or fuel pump may be bad....I had the same problem once I did the same thing with the starting fluid turned out that I was out of fuel lol

if it starts with starting fluid, fuel is the problem.

yea i checked if it was pumping fuel andit was fine. first i to out the hose that connects to the fuel rail and it was flowing so i connected it and thougt it was the injectors so i checked the injectors and they were fine. i dont no what else it can be

did you check the injector harness to see if it's still connected like it should be. Also check the fuel pressure regulator... if you have fuel going in the FPR and everything is bleeding out in the fuel return line without reaching the fuel rail and injector, you're likely screwed.... anyways, that's all I can think of right now...

yea i checked the psi of the fuel pump and it was only pushin 15- 20psi so that mite be the problem hopefully

Pressure should be 30-32 at idle. Clogged filter could cause this.

The main harness that goes from the front end of the car, around the under side of the passenger fender and into the car. Is there a break for that harness right after the harness goes in behind the dash?

There are only 3 harnesses on the car: Engine, Chassis, Dashboard.
The only connection is the super junction on the passenger side for the dash, and the engine connection on the driver's side and under the air filter box.

I just wanted to know where the connection is without taking the dash apart.

seishukuOct 14, 2010, 2:55 am · #15

Should be in the passenger side foot well, just under the dash
