1986 firebird fuel injection, injectors not working

Got a firebird that doesn’t start but cranks, fuses for the injectors are good. What should I do? I wanna get the car running as soon as possible. Everything else is fine.

yea I have spark but no power to injectors. I tested it by taking a small dome bulb and connecting it to the injector plug and no power

Have you checked for power with a volt ohm meter at injector plugs?
as well as impedance of injectors ? Not sure your dome light bulb can be used for a noid light. There cheap enough to buy.

has the car been sitting? The injectors may be "shot"

Re: 1986 firebird fuel injection, injectors not working

I checked that fuse and it’s a good fuse
Is there a way to see where the power comes from in the ecu and track it?
cam replacing the injector harness be a fix?
