Hey guys,
I'm at my wits end. I've got an 03 with the 7.3 and I can't figure out the cause of my problem. I've thrown a ton of parts at it from all the research I can find. It just cranks but won't start. If it does start it will idle all day, but if I try to drive it I'll get about 5 miles and it dies and won't start again. All the issues started one day while driving home. The truck started blowing white smoke and died. I try to start it an it would just crank. Then it wouldn't crank. One of the cylinders hydro-locked (Didn't know that at the time). I tried to crank it again, heard a loud pop and the truck started but was making a hell of a racket. Got it home and pulled the valve covers and discovered a broken rocker arm. While I was in there I changed the injector seals (they were in horrible shape), changed the glow plugs, changed the leaking HPOP gasket, did an oil change, and put it all back together. After a few minutes of cranking, it started an I went for a test drive to burn the oil out of the cylinders. A few minutes into the drive, it died and wouldn't start. Towed it home and started researching. Changed the ICP, rebuilt the OPR, changed the CPS, and it started. Samething, test drive and die, tow home. Hooked up the code reader, no codes. Checked the LP oil res, and it was full. Decided to change the LPOP as well. Passed the injector buzz test, checked the glow plug relay, all good. Cranked and cranked, no smoke out of the exhaust. Finally after running the batteries down and recharging them and cranking a lot more, it started. Same result, 5 miles and died. Haven't been able to get it to start back since. Dealership can't get me in until next Thursday 8 days from now. Oh, should mention I put in new batteries as well. Any ideas or help would be greatly appreciated! Thanks!
