Round 2?
This is a continuation from the other thread that I started called "Round 1"
The truck is an early '99 F-450. I put the new batteries in, started doing some other looking around under the hood and found that the nut had come off the IPR and fallen into the valley. So, I removed the IPR and cleaned it and re-installed it. The truck is putting out a lot more white/grey smoke while cranking, but it is still not starting. It acts like it will catch, but won't quite do it. One other question, which way is the selinoid supposed to face on the IPR? I could have re-installed it backwards. Does anyone have pics?

I would suspect that someone had the IPR out and forgot to reinstall the nut. The truck may have been sitting so long becuse of a High Pressure Oil problem that the PO could not figure out.
I hope someone will come along who can lead you through troubleshooting the HPO system. Do you have anyone that can loan you a known good IPR?

Well, I swapped a good CPS and IPR in and still nothing. Finally got to messing with the fuel pump and discovered that it has quit pumping fuel since this all started. It runs, just no fuel, so tomorrow I'll try to get my hands on another pump.

Check for power at the fuel pump Mike. Electrical issues can cause the fuel pump not to recieve any voltage, so don't waste money on a fuel pump unless you know the pump is getting voltage. You can guess how I know this.

you, Chris. Yeah, I checked that. The funny thing is that it spins it just won't pick up fuel. We pulled it off the truck and hooked to a battery with a 2 ft. length of hose into a bucket of fuel and it would sit there and spin and wouldn't pump a drop of fuel. There is no restriction in the thing because you can blow air all the way through it with no problem from the inlet side. You could stand beside the truck and hear it run, but when you opened the drain valve on the fuel bowl only a trickle of fuel would come out. That is what clued me into the fuel pump.

Good diagnosis! The PO probably messed with other things and gave up. I may be you got a good truck for some of your time and very few parts!

Well, it's running. Now all the interior is completely out of the truck and we are doing a complete detail of all the interior and exterior. The new fuel pump did the trick, it was not the only thing wrong, but for $3k plus $180 for a new starter and a fuel pump with less than 50k on it it's running so I think I came out okay. By the end of next week it should look like a completely different truck. Thanks to all of you who helped to kickstart my thought processes.
