I replaced the starter and the truck worked fine, then started acting sluggish a couple weeks later. I will check into the relay though. Thank you

My friend suggested that I should, he supposedly knew a lot about Ford Diesels. Should have known since he drives a Dodge!! I really don't know anything about Diesels yet, I have only had the truck about 4 months. It was given to me as a gift.

Do a voltage drop test on the cables and the grounds for the starter.
Things can "LOOK" good and still be hiding some nasty corrosion
under that nice looking insulation.

Here is a Youtube video.

Also there is a relay that is part of the CJB (Central Junction Box) that you
can't replace. If that one goes bad they you replace the CJB.
I'll put the starting system for the 03 up in a PDF file for you to look at.

There are a few other things that cause a no start. Your going to have to
do some testing.

EDIT : Reasons to not do to your Ford the thins the Guy that drives a Dodge says to do.

I would try unplugging 3 wire sensors under the hood one at a time and attempt to start with them unplugged, start with the clutch fan connector.

I think he is dealing with a No Crank. And that will lead to the No Start.

So to clarify. Do the truck crank or not?

Contrary to popular belief, it is sometimes cheaper to take it to a trusted dealer. It's your responsibility to find a trusted dealer.
