Won't start after sittting for days. 7.3 PSD

[littleestowing]

I have a 96 7.3 PSD. After it sits for days it won't start in either cold or hot weather. I has a newer Jasper rebuilt motor in it. I bought the truck and the motor only had 2k on it and it was that way then. No I haven't check fuel pressure or anything else. I want to know where to start. I have check the fuel filter and it has fuel in it. I know the injectors work from oil pressure but, where does it get the oil pressure from and how do it check it? Any help would be appreciated. Thanks in advance. Dave

Sound like this happens often? How do you eventually get the truck running?

I have seen some threads about non-starting being a High Pressure Oil Pump (HPOP) problem???

Its possible the reservior is leaking down on your high pressure oil pump.

How do I check the HPOP?

Remove the pipe plug in the top of the high pressure oil pump reservoir and inspect the oil level, should be within one inch of the top. If it isn't top it off. I will see if I can find a pic for you so you know what your looking at.

I sure I know what it is. It does sound like that is what it is. If so how can I fix it or should I ask. LOL

Here is a pic of the engine showing the high pressure oil pump and reservior at the top of the page. There is a pipe plug with an allen head you remove. I don't know the fix if it leaks down.

This is at the front of the engine under the plastic cover.

I have read alot on these forms about the IPR what is it? Also I forgot to mention sometimes it does start runs rough and quits and won't refire. I know better then to use either because of the danger of blowing apart the glow plugs and drying out the cylinders but, if I mist it out in front it will tries to start and if you keep misting it it will then contiue to run. This is the only way to get it going. WD40 won't fire it.
