Hi my 04 6.0 ran fine parked it for about 2hrs got in and wouldnt start. it turned over just fine. i checked fuses they were good. i hav a bully dog programmer so i thought id take that out and put the stock program back in and see if that would make a difference. now the truck wont turn over put the bull dog program back in still wont turn over. its like the computer isnt turning on. i have read stuff on here and you guys know your stuff. im hoping someone can help me out

 

The tech folder at the top of this forum marked "read first" has a no start checklist,best if you read it first before we try and figure out what is going on with your truck.
