Just went and looked at an 06 PSD F350 with 100k miles flat on it. The dealer said that it ran fine and would do everything perfectly, except after you turned it off it would take about 1 hr before it could be started again. He said that a mechanic said it was more than likely the HPOP. I'm wondering if it's the HPOP itself or if it's the IPC..ICP (sorry can't remember which it is) that is broken? Or does it sound like something completely different? He said he'll knock 2grand off the price if I buy it and fix it myself..I know an HPOP replacement won't be that much and especially not the other thing (IPC..ICP), so I could make a heck of a deal on it if that's all the issue is. Does this sound like an HPOP related failure to you guys?
