Ok here it is took the car out yesterday, it started up fine ran a little rough at first but it ususally evens out and is fine , well I figure i would adjust the fuel preasure down, so took it apart did it then back to gether and it started , so i shut it off put the air intake back on and tried to start it again , would start just turn over , I have to stand on the gas and then it will start but it runs absolutley horrible will not Idle at all. after it runs for a while , it will seem to run fine but as soon as I shut it off and start it back up same thing. any ideas???/

I am stumped!

Same thing happend to me today! I jsut got out of the store and was going home. Turned on my Z and it would harldy run? Terrible idle! then it died! I run a supercharger on it, however it's off right now. Anyway, I have an aux. fuel pump on it so I grounded it so it would be on, then the car limped home...barley! I"m thinking its' the tps sensor? I"m gonnna check that, fuel psi, and my coil. Keep me posted adn if anyone can help.......please do!

 

not tryin to be mean or anything...but did u set the timing?

 

EVerything is perfect! timing was set @ 6deg advanced. It's either the pump or relay. I have no psi when the engine is off and the key is on. Is there a way to test the fuel pump by adding power to the aldl unit?

 

well if your car is TPI Forza, then it is probably your MAF, or your TPS, if it throws any codes run them and find out

 

NOPE! Checked the tps...fine. changed map sensors..fine. put a fuel gauge up to the rail and i have no psi when teh engine is off adn key is on. Checked the relay, not it either. Looks like a long day ahead of me changing the fuel pump ForzaAzzurri, I suggest you putting a fuel psi gauge on the car and see what it's doing. You may end up as I have..hope not!
