I replaced a fuel pump on my truck….now I have no power to the fuel pump, I checked the fuel pump relay, it is good, however the fuel pump fuse next to it is getting no power to it. could I have a bad pcm possibly?

  1. The PCM provides the trigger voltage(secondary voltage) signal that provides power to the fuel pump fuse. So check the PCM fuse. Then check for good battery voltage. A weak battery will not allow the PCM to activate the fuel pump relay and turn n the fuel pump.
