I'm doing an ls swap into my Monte Carlo SS (86), I have a stock 07 ls2 im getting 80 psi fuel will that stop my injectors from working??? When I crank it the engine doesn't fire up, i sprayed starting fluid and the engine fired right up. I Need some help please.

I'll just uncap my return and tie end to it. So once I get the pressure right my injectors should kick on or do you think they are possibly clogged ???(I had the engine at least 6 months before I installed it)

If you have fuel at rails and pressure is okay. The only things that can keep out of the motor normally would be injectors stuck or EFI computer/harness issue. Put a test light in place of the injector and crank it, light should pulse. If it pulses, just injectors with a 9 volt battery.

Sounds like during cranking, there is no power. Make sure there is power WHILE cranking AND after startup.

Yeah, really old cars with points you can have an issue trying to install EFI because some things don't maintain power while cranking. The ECU, injectors, fuel pump, and coils must have power while cranking. If it has power with key on then you likely have an ignition switch issue or maybe a weak relay. Oh, unless your voltage is dropping below 10 volts, sometimes it's 8 volts that is an issue, but if it stays 10 or above it's not a problem.
