Hi im having a problem with my early 04 6.0. I just purchased the truck two weeks ago from a local dealer as-is. The truck started fine idles great but has the no start when hot. I had the same issue with my last 6.0 so after some negotiating I purchased the truck. Truck has been studded and has egr delete. My problem is they said they replaced the dummy plugs and a few other gaskets trying to resolve the no start when hot issue. This weekend I was driving on the interstate and all the sudden the truck wouldnt accelerate then it died as I was getting on the off ramp. Towed it home went out the next day cranked it a few times no start. After extended cranking it started I cut it off and waited a few minutes and tried again it started right up. I removed the hpop expecting to find bad o ring s but they were fine. Ipr screen is intact. Is there anything else I should check before buying a new hpop? Im also thinking they changed the oil and maybe used the wrong weight. Any help would be greatly appreciated.
