My 1991 Suburban no longer wanted to start after sitting for about 2 weeks. There is no activity at the fuel pump and even if i bypass the system and run the fuel pump there is no gas that gets injected into the carb. When bypassing the devices they work but there seems to be an electrical problem preventing the fuel system from working together. All fuses were checked and the relays in the engine compartment were physically wired and tested.

If you manually power the fuel pump, does it produce at least 11 PSIG at the injector pod?

yeah there's for sure enough because when i power the pump and then power the injector the gas sprays like hell. i'm leading towards an electronic problem

Is the vehicle equipped with a PASSKey system? If so, does the SECURITY lamp falsh while attempting to start the engine?
