I recently put a new GM fuel pump, filter, relay, and new fuses in my vehicle and it was running fine. A couple of weeks later my ground grid had to be replaced- all wires were directly grounded. Now when I turn the ignition switch to on position I can here the pump working- but my car will not start and fuel rail pressure is low. Please Help!
have the same problem?
