GMC Troubleshooting Questions? Ask a Mechanic for Answers
It does crank. The problem started when they ran it out of fuel. So far I have drained tank. Installed new filter. Primed with hand primer. Seems like there is not enough fuel pressure at injectors. If I loosen nuts on injectors one at a time and crank it does not spray fuel. More of a water fountain type run out between nut and line. I have cranked and hand pumped. And still no better. I feel it's the pump. Or something restricting the flow.could the computer be bad? Where is the fuel shut off soleinoid? I have no power at the one electric plug on pump.
