AAAARgh! Ok, I have a 2005 6.0 POS PSD that is currently sitting in my driveway in a no start condition. Here's the history:
The truck was working great up until a couple of weeks ago. We pulled the 5th wheel on a long trip and after getting home, parked it in the driveway. The next day the truck wouldn't start. I immediately suspected the FICM, and ordered new guts for a rebuild. Those came in, I rebuilt the FICM, installed it, and it started right up. Next day, no start again. I suspected I may have jacked something up, checked all the connectors, etc, but found nothing. Finally got a code reader and pulled a low ICP pressure code. I replaced the ICP and boom, started right up. The truck ran great for 2 weeks, and then this morning, crank no start again! I am not pulling any codes at all. I don't have an advanced code reader - just a basic Bosch, but the normal codes will come up on it and I'm getting none.
The batteries are charged and on a crank, I am not getting any oil pressure on the dash gauge, which probably isn't a good thing - the tac does move, but that probably doesn't mean much.
I'm not a guy that most would consider a wrench - I'm on a serious budget, though, and cannot afford to run the truck down to the shop and would prefer to do the work myself if I can. I suspect an oil leak, probably the STC connector, but want to test it first. I need some advice and pretty basic step by step instructions or videos on how to do that air test. I'm also wondering about the IPR valve and, if that is bad, if that's a symptom of a bad HPOP?
BTW, I just spent 2400 on replacement injectors, too. I'm anal about oil, and am running Rotella full synthetic (changed every 4k) and new Motorcraft fuel and oil filters, installed in the last month.
I'm definitely not wanting to throw more good money after bad into this truck, but if it's a fix I can handle, I'll do it and gladly drive it another 100K. It's paid off and has 154k on it now, so it's still cheaper to fix it than to buy a new one. Any help you guys can offer will be greatly appreciated. Please use small words - I'm not a tech!
