Hi there,

This is a very common problem when the glow plug relay becomes burnt inside from arcing and then no longer allows the full current flow through the relay to the glow plugs.

This then give you the symptoms you have of lack of glow plug operation. It could also be some bad glow plugs, but on your vintage of truck the relay has to be replaced at least two times before you ever begin to have a bad glow plug.

You only want to replace the relay with a Ford part as the after market parts are generally low quality and don't last.

Let me know if this all makes sense and if you need anything further at all.

Sincerely,

Ron Wiggins

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.
