Well, no good deed goes unpunished. Long story short, lent my truck to buddy to go camping, and of course it ####s the bed. No power, hard start, HPOP issue it seems. Pulled the IPC plug and same issue. Hard start, (hot or cold) IPR duty cycle is high, 85%. It's an 05, with the upgraded dummy/stand pipes and fittings. I haven't been into it since all the upgrades (3 years ago) I put a new IPR at that time. So I guess my question is, what am I looking for as far as leaks? I haven't got my hands on the rig yet, as it's 16 hours away stranded. I'm on my way to it now, and wonder what I should grab for parts in the way. At this point I'm praying it's the IPR as the IPC seems to have no bearing, and working fine. Because if it's more than that, it's going to get expensive fast. Any ideas?
