tbi not spraying now

[74propu]

fixed the wiring to the fuel tanks and pumps injectors was spraying but the distributor was 180 out re stabbed it and it fired right up then shut off no spray at injectors checked to see if I was getting fuel to the tbi and it is but nothing coming out of the return line back to the tank what could have stopped it from working

What I'd do:
1. Check to make sure your fuel pump is buzzing when the key is first turned on, or I believe you can apply 12V to ALDL pin G (bottom left) to see if you get fuel to the base of the TBI. Could be relay or pump itself.
2. Check for injector signal with a noid light.
3. Test your ignition control module, or have it tested.
4. Only other thing I can think off the top of my head is the oil pressure switch.

That's just a rough sketch of what I would play with. Definitely make sure your pump is coming on, though.
