Hello, long time lurker, first time poster.
Yesterday I replaced the gaskets and o-rings on both my HPOP and IPR, putting new o-rings on the oil line connectors coming out of the HPOP as well due to a very large oil leak. Now the truck won't start. HPOP reservoir is full we filled it before trying to start, fuel filter bowl is full, filled it as well. Tach is moving, oil pressure is reading in the middle of the normal range on the oil gauge. No smoke from the tailpipe at all. Voltage on the batteries are 11.5 when cranking. Fuse #22 and 17 are fine and the truck has a new fuel heater on it a couple of years ago (before I decided to start working on the truck myself). However we are hearing a wierd noise coming from the HPOP itself...it is possible that with 280k miles on the truck taking the HPOP off and moving it around did something to it and/or the IPR (loosen up some trash or debris) and damaged the pump? I'm picking up a 3000psi gauge today to check the oil pressure on the lines going to the oil rail to see what type of pressure I have. I put an injector in a couple of months ago and it was hard to start after doing that, but only had to turn it over on and off for about 15 min before she fired right up (didn't know about filling the reservoir at that time) and has run like a champ before this.
HELP PLEASE!!!! any other ideas would be great.
