Re: 89 IROC Fuel Problems?
Assuming the ECM, relay, pump,etc are OK, try checking connections to the Oil Pressure Switch
If that comes unplugged, or is bad, no signal will get to the fuel pump from the ECM.
This is a safety feature: If the engine has no (low) oil in it, it will shut down the Fuel Pump to save the internals..
