OK for starters got the truck for a good deal and needed some work . Well it would only start when it was plunged in no matter what the temp was so I put new gp and gp relay valve cover gaskets and wire harness .figured it would start right up but nothing . So I tryed unplugging the ots and and still nothing well then I unplugged othe ICP and it fired and ran like crap idle was all over the place till I plunged it in . Thought I had found the problem shut it off and went inside. The next day tried the same thing and nothing just a few pops is all but the check engine light was on then. I'm really at a loss first diesel I have owned but it is well worth the price I paid 01 f 350 turbo 7.3 4x4 xlt lariat 4door 8ft bed and rust free 800$ so I hope I can get some help on this and thank you for your time
