How To Ford Fuel Pump Driver Module Bypass
If you have a Ford that uses a fuel pump driver module, it can be bypassed for testing.

This can be a good way to test if the module is bad or possibly get the vehicle home in an emergency.

I recently ran into this problem with a 2008 Ford F-150 that had a fuel issue.

The code on an OBDII scan tool was a P1237 Fuel Pump Secondary Circuit Malfunction

The fuel pump driver module is located at the rear of the vehicle.

Before bypassing the module be sure it is getting 12-volts DC or there is another problem.

There is an inertia switch on the passenger side of the 2008 Ford F-150 that controls the fuel pump along with relays in the fuse box.

  • Pin 1: Fuel Pump Driver Module Monitor
  • Pin 2: Fuel Pump Motor
  • Pin 3: Ground
  • Pin 4 Fuel Pump Motor +
  • Pin 5: Inertia Fuel Shutoff IFS Switch. Switched Power Output

The pins are not numbered in a line, so it can be a bit confusing but below is how it is wired.

Be sure to see a diagram for the make, year, and model of your Ford, as there may be variations.

The outer wires of the plug are 12-volts from the battery (white) and module ground (brown).

Jumper the grounds and together and the 12-volts to the 12-volt for the fuel pump will bypass the module.

Basically, the outer left pins and outer right pin are jumpered together.

Summary
Jumpering a 2008 Ford F-150 fuel pump driver module is straightforward by sending 12-volt and ground to the fuel pump.

First, Google a wiring diagram for your Ford to be sure the wiring is the same.

The jumper is likely the same across many types, but it is best to check a diagram to be sure.

If the fuel pump is not working, be sure to check for 12-volts on the white wire, or the jumper will not work as the module may be good.

Common Ford OBDII codes for a bad module include P1237 Fuel Pump Secondary Circuit Malfunction and PO191 Fuel Rail Sensor.
