need help with 89 GTA 350 TPI
The car was working fine, I stopped and went inside somewhere and it would not start up and keep running any more. It will crank over and start and die imedietly. I have changed the Fuel filter, and Fuel Pump.I get 42 PSi on the fuel rail. I have bypassed the VATS system in the past. I can spray fuel into the intake and the car will run, as soon as i stop spraying the fuel, it dies. I have also replaced most of the fuel injectors in the past. If you have any ideas about what could be happening please let me know.

I have swapped out the maf already but i can try again. I will have to try cleaning the iac. The SES light comes on when i turn the key tot he On position but then goes off. I have had problems with the VATS in the past and had to bypass the system with resistors. If you have any other ideas keep them coming. i need all the help i can get on this car.

You said you have replaced some injectors but not all? Check the injectors and see if you have any bad ones. I had a similar issues and it was bad injectors.

Re: need help with 89 GTA 350 TPI
this is what solved my problem. Thank you. I checked the injectors today and the only three that i did not replace 6 months ago where the ones that went bad. After replacing them the car will start and run smooth. thanks again.
