Hello and welcome! My name is ***** ***** I can assist you with your question. I would start by checking for power going directly into the fuel pump driver module on the white wire with the key on and cranking. If there is no power, check power going into the inertia switch and check power going into the fuel pump relay. There should be two powers and one ground. When this happens the contacts inside the relay will close and it will send out power on the fourth wire to the fuel pump/inertia switch. Here is a wiring diagram.

What Customers are Saying:

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

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.

9 dollars, 2 hours of my time, and I drove away. Your diagnosis was right on the mark. Thank you so much.
