My truck wasn't starting last week so I came to you guys and with your help figured out the FICM was bad. Got the sent out to FICMrepair.com and replaced . On a side note I highly recommend Ed at ficmrepair.com! He got my repair done same day and overtightened the part back to me bc i needed the truck running asap. So after I get everything back together I went for a test drive, turned out in front of my house got on the throttle and it stalled. The truck went back to cranking and no start.

So I had it towed to a shop for diagnostics. They said the high pressure oil was only reaching 50 and that the pump needs replaced for $1700 parts and labor. Is it possible this could be caused by a leak somewhere in the system or something else? Ill prob end up fixing this myself to save labor but the pump still isn't cheap. Just wanted to see if there are any other possibilities. Also does anyone have a procedure manual for pulling this pump and the torque specs for installation.

 

Can't condemn the pump without more information.

ICP readings with IPR duty cycle.

Then conduct an air pressure test of the HPO system

What year model is the engine?

 

The truck is a 2004 F-350 6.0 PSD. What do i need to do to check these things? I will talk to the mechanic some more when I go to get the truck.

 

Is it an independent shop?

Do they have access to the repair manuals?

Do you know where the ICP sensor is (the early 04's had them under the turbo, the late ones have them on the passenger valve cover)?

 

It is an independent shop. I don't know if he had the service manuals or not. Yes I know where the ICP sensor is. Mine is under the turbo.

 

Since you posted an ICP value (I assume that the 50 is really 50 psig??)

You or he needs a scantool that reads IPR duty cycle along with the ICP - it could just be an IPR stuck open.

After getting the readings (and assuming it confirms low HPO pressure and the IPR valve looks like it is working), then he would need to remove the ICP sensor and add pressurized air 100 psig) to the ICP opening. Listening for leaks might indicate the problem area.

I just don't see how ANYONE can condemn an HPOP with only an ICP reading. Are you confident in the shop?

If you are going to fix it yourself, then buy a scangaugeII (or better yet an autoenginuity), do the troubleshooting yourself. You would probably be better off removing the turbo to do the air pressure test.

On the early design HPO systems, the HPOP cover and the HPOP dioscharge connection are common leak points IIRC. It could also be an injector o-ring (at the oil rail connection). I admit it could also be the pump, but I wouldn't want to recommend throwing parts at it (unless you just want to replace things for future reliability).

 

Yes that reading was 50 psig sorry forgot to include that. I will call him when the shop opens and see if he got the ipr duty cycle. Then try an air test if it is needed.

 

Talk to the mechanic again he said the IPR duty cycle was 85. After talking to him he told me worst case was the HPOP but it could also be a leak. He said it would cost me 300 for him to do the pressure test, so I think I am going to tackle it myself. Is there anything else I need to do other than make and adapter for the ICP port?

Also will the Edge Insight CTS data monitor read me the data I need? I was looking into buying one of those anyway.

 

Not shure about the edge but I know that the Scan Gauge will get you the readings you need

Was there any other recent work done like maybe an oil change anything

 

Yeah about 2 months ago I had the oil cooler fail on me. I installed a bullet proof diesel condernsor mounted cooler to correct that.

Here are all the other things I installed during that rebuild all bought from the bullet proof web site.

ARP Head Studs
Ford Head Gasket 18mm
Rocker Carrier Gasket
Fuel Injector O-Ring kit
Ford Rocker Arm clips
Fuel Filter seal kit
Oil Rail Dummy Plug
Oil Stand pipes
Fuel Pressure Regulator Kit
Turbo Oil Drain
Egr Cooler
Air Intake Gasket

I think that's about it. I dont remember if the stand pipes were the uprgarded ones or not. I didn't know there was an upgrade until recently.

 

Well thats sucks Dang truck just dont want to cooperate recently

I am thinking it could be IPR relaited since the recent work and collected some junk on the IPR Screen and caused it to build Great Pressure and forced junk threw the IPR valve and now its stuck open

I would be for pulling it out and checking the IPR out

Motocraft oil filter has the oil been changed recently the filter is very important on brand

 

That is what I forgot to tell you. I installed a remote screw on oil filter. Its mounted inline just before my new oil cooler. And i have only been driving a month since that got put in.

I actually have the ipr screen and seal kit i forgot to put on when I did all the other work. I plan on checking out the IPR and air checking the hpo when the truck gets towed back home tomorrow. The video I found posted by bismic showing how to do the air test says I need an adapter with part number 303-765. I searched for this online and they are all around 60 bucks. Is there anything else i can use for this or somewhere I can get it cheaper?

 

I dont know anything about remote oil coolers and the bypass filters to be able to say a issue could develope there. Or what to look for either

What goes in place of the Stock oil filter??

Also if you find that the IPR screen is plugged or pushed inside alittle or has a Hole in it you should replace the the IPR Valve because the Guts will be jacked up and by just replacing the screen will not fix

 

I would almost check out the IPR Valve itself first its very common to trash this valve after any majoir work like you have done. You may find it to be the issue and not have to air test.

I havent done an air test but thought the adapter was just something cheap IDK could be wrong

Maybe others that have crossed this Bridge B4 will chime in here

 

There is nothing in the stock oil cooler anymore. It is purely a place holder for the secondary fuel filter now. The new oil cooler setup replaced the original oil cooler cover.
