Hey guys im having problems with 08 dodge 6.7. Will a map sensor cause a truck to go into limp mode?when i start the truck for the first time, it doesnt matter what time of day, it will die about 5 times in 20 miles then clear up an run good.i have replaced presure relief valve, cascade valve an fuel rail pressure sensor.i have ran a few test such as,injector pressure test,fass fuel pressure test an both are right were they need to be. When the truck dies it doesnt sputter,miss,or knock just simply dies with no codes. Im sorry about the writting im using a phone. But any advise will help thank you an sorry again.

 

Do us all a favor here.

Re-write that post, and break it into sentences. Use things like periods, commas, and perhaps even question marks.

You have a smiley face at the end, but no punctuation...

Sounds like possibly something electrical. A buddy of mine has an 08 and there is a fuse under the hood on the drivers side in the TIPM that has a little white plastic clip around it. If that one is loose or wiggles around, the truck won't run. I want to say it was power for the module that recognizes the chipped keys. I would check that as well as the big bundle of wires that plugs in to the TIPM. Are both your batteries tight? Do your lights shut off when the truck dies?
