Truck had hiccups like it was getting enough fuel , was told it was CPS so changed it yesterday. Went to go out this mourning and truck ran rough and died . Got it restarted and back home still running rough. This is first time SES light came on , so went and rented scanner and it said scan passed and no codes . Restarted again , ran rough and SES come on again . Recheck scan no codes , I am at a loss any help/ advice would be greatly appreciated.

 

Your local autozone code scanner will not pick up our codes, our trucks are not fully OBD2 compliant...

Without a good code read I would bet you have a UVC issue, easiest way to check is to unplug one side and try again, then the other... see if it gets better or worse.

Low fuel pressure will not cause a miss so to speak, low ICP will not cause a miss so to speak, but a bad electrical connection will every time.

Get a tube of Dielectric Grease, every connector you can pull apart on the truck should be packed full of that crap.

 

New to diesels what uvc ? bought it used was looking and found loose connector dont know for how long but cannot find anywhere that it should belong . Someone put pyro and boost gauges in it , would they have unhooked something to do so ? Bought truck w/232000 ran sweet till the other day , put a little over 7k miles on it changed oil , air filter and fuel filter , really wondering what went wrong , will go and pack connectors see if that helps thanks .

 

UVC is the Under Valve Cover Harness

 

So I bought this truck used , come to find after weeks of trying to hunt down issues I determined my PCM was bad . Today I pulled out the PCM , only to find a PowerForce chip . I proceeded to call them about their chip and was told they dont make it any more or warranty their product . I pulled their chip and reinstall the PCM and wa-la my Stroker lives again , ::fired right up no SES lights zip , nada , man I am one happy **** ! Thanks to all for advice . P.S. Now I really need to win some of that BITCHIN stuff in the free giveaway so I can have a few more ponies in my beast.
