Here is the testing procedures

First check for any PCM codes and address as needed.

Then check for any codes in the restraint control module. The restraint control module is wired directly to the fuel pump driver module and can disable the fuel pump.

If there are no codes in either module, access the fuel pump driver module.

Unplug the driver module and perform the attached bypass procedure.

Attempt to operate the fuel pump and start the engine.

If the fuel pump still does not operate, check the power and ground to the fuel pump while the bypass is still in place. Note the power comes from the fuel pump relay, which is powered by fuse 27. If the power and ground to the fuel pump are ok, yet the pump won't run, replace the fuel pump.

If the fuel pump runs and the engine starts with the bypass in place, check the wiring between the PCM and the fuel pump driver module before suspecting a driver module failure. In most cases, if the fuel pump driver module is replaced, it is a good idea to replace the connector for it as well.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
