Hello and thank you for your question. My name is James.

Does your F-250 have a glow plug control module, or just the relay on top of the engine?

I sorry it was the injectors not firing I changed a battery and it's starting now maybe low volts
Ford Mechanic: 6Bucs, Ford Senior Master replied 10 months ago

Oh ok. The IDM won't activate the injectors without at least 250 rpms signaled from the cam position sensor. If the battery voltage was low, the engine might not have been turning fast enough to make the computers happy.

Did you need any assistance then? If something else comes up, you can always post back here.

James.

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.
