i've got a 2005 6.0 that won't start unless you give it a shot of ether then runs great but then it will also just die going down the road occasionally won't start with out ether then will run fine after running. i have replaced the cam sensor changed oil and fuel filters also.

 

DON"T spray anymore either in it! You need to get a scanner and see what your ICP is while cranking. Also you can try unplugging the ICP sensor and see if it will start.

 

Where is the icp located at ? I know i shouldn't use either but it beat walking at the moment. Thanks for the advice will check this out.

 

Its in the passenger side valve cover. I want to say they will start on WD40 and it is easier on the engine

 

Thanks i appreciate the help will be checking it out tomorrow.

 

Any update?

 

started fine this morning then wouldn't start after it was warm even after setting 2 hours . Feeling kinda dumb but i couldn't locate the icp. Also i was going to add i had a edge box on it when this all started but that was the first thing i removed when i started trouble shooting.

 

It is a grey plug on the passenger valve cover towards the front of the engine. I think your gonna need to put a scanner onthe truck to get anywhere if unplugging the ICP doesn't cause it to start.
