Hello, not sure if you have TBI or CPI fuel system? If it is TBI, check for an injector spray pattern, the pattern doesn't say much about fuel pressure, but, it should mean there is an rpm signal, at least. Without the rpm signal there may not be any spark at the plugs or injector pulse. With the engine cranking, do you have spark at the plugs?
