ipr question

I've been reading that a stuck ipr can cause the icp to only register about 200 psi while cranking.

I'm wondering if it could also cause the oil pressure gauge on the dash to register no oil pressure or would it still have enough low pressure oil to trip lpop pressure switch?

Should be able to make low pressure oil even if the IPR was bad.

Maybe check low pressure oil with a manual gauge.

The low pressure oil system and the HPOP oil system are 2 seperate systems, each has it's own pump and regulator system. They do however work in conjunction with each other in this respect. The low pressure pump provides the oil to the HPOP resivoir to keep it full of oil for the HPOP to use.

So should the Lpop fail to pump enough oil to the resivoir it will affect the HPOP system out put.

FYI the dash gauge is little more than a idiot light which is one of the reasons everyone recomends getting real gauges or a monitoring system. The dash gauge registers from 7 psi when it registers at all. Not much oil considering the min recomended pressure is 45 psi at the filter houseing.

I agree, definetly check lpop pressure to eliminate that first.

I'll try and find a spot to hook up an oil pressure gauge. I've been having a no start issue. I've also noticed that when it wouldn't fire that it was showing no oil pressure on the dash gauge. i didn't have a scan tool with me when it wouldn't start so i have no idea what was keeping it from starting.

If you look at the oil filter base bottom middle there is a test port. There is a 12mmx1/4 npt adapter available thru many hydraulic hose supply shops. Or you can get the ford one for twice the price.

You can pull the oil temp sensor or the oil pressure sender to gain access for a oil pressure test as well.. Just may need some adapters.

03 do you have low icp hot or cold? Does it not run at all? On an early diesel you can leak enough oil out of HPP for it not to show up on low pressure side. To determine high side or low side problem def test oil Pressure in the EOT port if your low pressure is good I would suspect IPR or high pressure pump. The early years do some weird things.
