IPR Question
Searched, posted and searched some more. The verdict is back on my truck. Hasn't started in about 2 weeks. Last week I was waitin on a guy who said he was gonna help me fix it but never came through..
Anyway, dealer says $1500 for new IPR and HPOP. Now 3 weeks ago they tested the pressure in the HPOP and said it was good. They said the IPC was giving irradic readings between 300 and 500 which means that the IPR could also be bad which would in tern cause the HPOP to not work properly.
Now the dealer is saying the HPOP is bad, only putting out 150 psi and should be 800 psi. When I asked about the IPR, they said they did not know if it was bad but recommended that it be changed " to be on the safe side".
Can anyone tell me their opinion on this. I have already replaced the ICP and CPS sensors. Will a bad IPR affect the HPOP pressure?

These HPOP's are pretty tough. Just don't hear of many failing. It does happen, just not much. My reading were all over the place when my IPR was failing. Granted I didn't do the reading nor was I there. The work was done by a trusted mech/friend of mine and he was leaning toward the HPOP for a while. Then after doing some more readings and test, decided to go with IPR first, Wah Lah no problems and engine never ran better.

I would not buy another pump until I knew for certain that is was the problem. I bought a brand new IPR and an ICP off ebay for about $120 total.

The last time it didn't wanna start a mech I knew told me to unplug the EBV sensor, I did that and the truck started right up?!?
Got it home and the next morning no start at all just cranks. Already put new CPS and ICP sensors in. Just found a IPR for 175 on ebay. Good deal or no??

No starting problems...I got them just to have in the tool box in case I need them.
I just posted because your first post seems a little fishy the way the dealer reversed themselves. The post reads like they know that the IPR is the problem, but they've decided to try to seperate you from your money. Don't know if that's the case, but it's the impression I get.
At any rate, changing the IPR is not a terribly difficult driveway task provided your socket is deep enough. To me it's easily worth the time and effort of trying it. $175 is not a good deal. It is available through the dealer for about $185 http://catalog.powerstrokeshop.com/p...&subcat2=73145

Beast, Have you checked your battery(s) voltage? Mine would crank and crank, but not fire at all. Got a guy to check it and it turned out to be a bad battery. Put in two new ones and she fired right up. Don't know if thats whats wrong, but it is possible.
Hope this helps.

First thing I would check Is if the Reservoir Is full, Then I would Put A 4,000 PSI gauge On the High pressure oil rail and check the pressure. If i Got a reading of 250psi or less I would replace the IPR If i got between 250-450 Then I would Plug the HPO Line going to One of the heads If the pressure came up I would pull that Valve cover hook up the HPO line and look to see what injector was dumping oil. If the pressure didnt come up then I would switch the plug to the other head and see if the pressure came up.
The HPO is going some where you just need to find out where.

Both batteries were replaced 3 weeks ago w/ optima reds.
Here is a question. Would a bad IPR cause the truck not to start? Also would a bad IPR cause the pump pressure to read at 150 psi or is there aq seperate test that can be run to verify that the pump itself is bad?
I ask that because when I asked if the IPR was bad the service advisor said that he did not know and that the tech said that the pump needed to be replaced and we should go ahead and replace the ICP too.
