No Start

02 F250 super duty 4x4 7.3 Power stroke:
Just bought truck a month ago has 76K mile runs great I realy like it, plain to pull 35Ft fith wheel. A week ago I had stopped at a store and when I came out to crank and move up to load it would not start, would spin over real good oil pressure would jump right up. Turned key off then tryed again this time it cranked. After loading it would not for several tryes at one time it cranked and shut right off just like turning the key off, finely it cranked and ran like a charm nall way home. later that evening was traveling real slow and it shut off just like turning key off, cranked right back up, had no more trouble. What do I look for? I have removed and reinstalled injector drive Module relay thinking bad connection.

Sounds like classic bad CPS symptoms.

I second the cps. AND WELCOME TO THE SITE!

CPS go by an oriley store and buy theirs it comes with a warranty so if it goes out just stop by and get another replacement. Everyone else you buy one at doesn't do a warranty.

Thanks

Thanks everyone for info. Will get one and keep in the truck, plain to headout on a 2 week trip next week from north FL to PA pulling the 5th wheel.
Again THANKS

You may want to get a few. Keep one in the truck at all times.

check the other sites i think they were saying from fordparts.com cps was 25 + shipping.
