What year? What wiring in particular are you looking for? (Some years have a LOT of engine wiring.)

hi john,its a 97/98 im not entirely sure.
its fuel related because its stalling due to this problem.
maybe something around the injector pump.

I would suggest picking up the 6.5 trouble shooting guide from this websight. It provides a ton of insight into trouble shooting problems just like the one you are describing.

I think if you were to provide some more specific information about the stalling...
1. when does it occur?
2. How often?
3. Does this happen when it is warm or cold?
4. Does it happen when you are at spped or idle?
5. Is the PMD relocated away from the IP?
6. Have you tried changing your fuel filter?

At any rate, If you do provide that kind of info, The brain trust here on this page will most likely have some answers for you. They have always come through for me.

Also you may want to try the search function available to see locate past posts about stalling. I'm pretty certain it is a common theme.

Good luck
