Q: Wiring to fuel pump is dead

asked by on

The wiring that goes to the fuel pump is dead.

I’m guessing you mean there is no power to the fuel pump sending unit. With the ignition switch in the crank position, power flows through a fuse to the fuel pump relay. The powertrain control module (PCM) then closes this relay, completing the circuit and applying power to the fuel pump. The first thing I would check is the fuel pump relay and its corresponding fuse. If these items are okay, the PCM is not controlling the relay when it should. This could be due to a failed sensor, or an internal PCM problem. I suggest you have a trained professional, such as one from YourMechanic, diagnose and repair the electric problem that is occurring within the fuel pump system.
