did a tpi swap aloooong time ago its out of a 85 tpi i believe.. car just quit running(injectors are not firing) about 2 years ago.. never could figure this out.. just spent all day on it today(im sick of it sitting in my driveway not running). i have no power to the injectors at all.. i also put 12 volts to all the injectors to test and it still wont run.. in the last 2 years trying to figure this out ive put computer/fuel pump/ign cntl mod/ had a mechanic( the same mechanic that did the TPI swap) look at and he couldnt figure it out..

i checked the signal going to the computer from the dist.. 1.3 volts while cranking. car will run if i spray starter fluid in. computer has power and is grounded. check engine light is on while key is on.. did kragen give me a bad computer? im stumped on this. it seems like the computer is not pulsing the ground on the injectors, or am i missing something?

 

Are you sure you have fuel pressure? What about the fuel filter? Fuel pump relay? Fuel pressure regulator? Fuses for the injectors? I think the injectors are supplied with 12v and the ecm completes the circuit with the ground. Perhaps you have an old-fashion wiring problem.

 

yes i have about 45 psi . thats the first thing i checked lol. ive checked all the wires going to the injectors and back.. no breaks

 

The only other thing I can think of is to make sure you have good ground connections. Other than that, I'm out of ideas also. Sorry.
