Customer Question
Nstalled new engine in...

Nstalled new engine in my 2003 ford expedition. It appears that the fuel pump is not working. Hit the reset, engine will not start. Any suggestions?

Mechanic's Assistant: Has your car been stalling?

NO. Just recently installed the engine. Trying to start the engine. Fuel pump clicks, but will not start.

Mechanic's Assistant: Are you fixing your Expedition yourself? What have you tried so far?

No... I have a retired certified mechanic working on the engine.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Installed a new fuel pump several months ago before replacing the engine.

Hi, My name is Jay

Have you checked to see if you have power at the inertia switch when you cycle the key on and off? Need to see if power is getting back to pump and this is easiest place to check the power to pump without getting under truck. Let me know?

No power. Should l replace the fuse box. Can't get the relay out.
Ford Mechanic: Jaybird61, ASE Certified Master Technician replied 7 months ago

Did you check for power when cycling key on and off since you will only have power for a second every time you cycle key to on.

The fuel pump relay is part of the fuse box and is not a replaceable relay. The entire box needs replaced if relay is bad. This is very common.

No power to fuel pump. Could it be the fuse box. The relay appears to be soldered in place. Should l replace the fuse box?
Ford Mechanic: Jaybird61, ASE Certified Master Technician replied 7 months ago
The only way to replace relay is the entire fuse junction box replacement.

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.
