92 GT no start

[CMG92GT]

92 GT no start.
I have spark, fuel pump works but does not prime I have to tap the relay to start pump and it stays on. I have more than enough psi to run the car, but the injectors do not fire. I pulled a connector checked an old injector, no click or puffs of air. I can't pull any codes from the computer I changed the battery right before this happened so I'm getting 00 on the reader. Has anyone ever had this happen? How did you fix it?
Thanks Chris

So it doesnt prime with the key in the "on" position, and the only way you can get it to run is when you jump it via the test port under the hood?

Check for 12 volts [with the key-on] to the injector connectors. They get accessory 12 volts and a pulsed ground.

If you have 12 volts but no pulsed ground, check your TPS sig return to be sure it's around 1.0 volt.

And of course, see JRichker's Cranks but no start checklist.

Good luck.

scld I've never tried to jump the fuel pump from the test port, I'am not even sure how to do that.

HISSIN, I will check both voltage readings and see if I get those numbers.

Thanks Chris
