Alright guys and gals, to the point. I am using HPtuners to get my car running. Long story, short is took my car to a shop. They were dickheads and left it out in the rain with no decklid or hood. So exposed engine and air filter and all that jazz. I said **** em took it home got HPT. ever since I brought it home my injector pulse width drops to zero every time without fail after about 3 to 5 seconds of running. then my car chugs and dies. Every damn time. Things I have done. plugs wires coil ICM PCM with the same tune Changed everything on the tune. checked all signal wires to injectors from pcm all good. checked grounds. checked power to pcm and injectors
I am so out of ideas guys. Literally anything you throw at me i will try.
I think there is a base Fiero tune on HP forum. A 98 GTP bin file will also run the engine in stock form. Do you have one? If you get one can you flash your PCM with it? Also, Can u open a DHP bin?
No it wasnt. It was running rich but it was running. I am using a 2000 grand prix pcm. Both of them are. The fuel pump is an aftermarket one. Its a solid pump and brand new. I can hear it running and that whole jazz, the fuel pressure is what its supposed to be at, 48 something If I remember correctly.

Maybe they flashed a stock tune that didn't have the VATS disabled. If you send me a STOCK bin PCM I will throw a base Fiero code on it that should run the car. I have a DHP so I can't read a HPT PCM but I think a HPT can read a DHP programmed PCM.
