Customer Question
My F250 7.3 diesel...

My F250 7.3 diesel will not start when cold, even if it is 80 degrease outside. I changed the glow plugs 3 months ago.

Mechanic's Assistant: Have you checked the battery, particularly the terminal connections? Are they corroded?

Yes

Mechanic's Assistant: What year is your F250?

1999

Mechanic's Assistant: Are you fixing your F250 yourself? What have you tried so far?

Yes. I check the glow plug relay and cleaned the Mass air flow sensor.

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

I can plug in the engine heater and it will start.

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.
