I have an 89 GTA, 5.7 TPI. It won't start. I checked for spark, I have it. I checked my fuel pressure, I sit at @ 40 PSI, even when cranking. The car DOES start with starter fluid, but always stalls. I swapped ECMS, nothing. So I am guessing my injectors aren't firing??? What controls them?? I need to fix this car ASAP, so all suggestions are greatly appreciated!

Thanks,
Tris

BTW, I checked for computer codes, the only one in there was a 43, ESC, if I remember right. Hope that helps.

 

Using a noid light, check to see if your injectors are firing. With KOEO, you should have +12V to one wire on the injector connector. If not, suspect the INJ1 or INJ2 fuse in the under dash fuse panel. If voltage is present and the noid light it not functioning, suspect a poor injector connection to the ECM at pins D15 and D16. Good luck!
