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.
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.
Do the Following at Your Own Risk. While I did not have any Issues, I Can Not Be Responsible If Something Goes Wrong.

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.
