That would be oil pressure ...
There is a schraeder valve on the FPR to test the fuel pressure ...

Oops, I read fuel, but saw oil. No, haven't checked fuel pressure, what kind of fuel pressure should it have?

It should have about 40-60lbs at idle.

Ok, I'll check this afternoon. But, Would the fuel pressure have anything to do with the low oil pressure though?

Low FP can set the code , PCM is calling for ICP at 1000, seems to high to me ...THe IPR may not be responding properly ...

You might be able to give it a good cleaning. I didn't have any luck with mine and finally just bought a new one.

I've seen them on Ebay for cheaper. I got mine from Joey at Terminator for $200.

Unless you have the extra cash to use on an IPR test , I would take it out & verify the O ring on the small end is good & give it the shake test. (it should rattle). We are also assuming the oil is full( not in need of a change ) & diesel rated ..

I'll probably just get one and try it, I need to get thing running better. I'm kinda getting tired of screwing with this thing, if it wasn't in such good shape and long paid off, I'd get rid of it! But who wants a truck payment?

How would I go about changing the ipr once I have a new one? I've found several of these on eBay, from 65$ - 200$+. What one should I get?
