My fuel pump will not come on. The pump is good, I have checked and replaced the relays and fuses and the pump. I have also taken out the open circuit relay and jumped the poles between three and five and the pump then turns on when I turn the key to ignition, but upon removing the jumper and replacing the relay in the connector the pump no longer turns on. What could this mean? Is it likely that the ECU or PCM is bad?
have the same problem?
