2001 f-350 7.3. new cam sensor, new Ipr valve, new Ipr sensor, new oil pressure sensor. Newer hpop, driver side injectors are new.. and 2 on passenger side are new.. truck ran and then studdered and shut off. And won't start back and won't build oil pressure.. full of oil. What can be the issue? Help please. 😩

Welcome to PSN!
Did you do all that at once? When you say, "full of oil", do you mean the crank case or the HPOP? The HPOP should be within 1/4" of the top.

Do you have codes? Do you have a code reader? if not ---

1. Get FORScan scanning software for Fords (free) and an OBDII reader. Greatest troubleshooting tool ever! I do not have financial interest in this tool. I just love it.
$12 for the 1-year PC license (not necc) and $7 for the android. OBDII reader $20-$60.

2. DO NOT throw parts at it . . . if you must, then make them Motorcraft parts. Ford diesels are quite particular about their sensors.

3. Come back with the codes. Lots and lots of smart people here!

Crankcase is full have not checked the res for the hpop

Just because something is new doesn't mean it works ( I had a brand new Ipr that ended up just not working)

I just now finished putting the other two new injectors in. It seems like they are sticking open and allowing the truck whenever it idles down to just die because the oil pressure is so low. And then whenever it dies it does not want to start. So I am going to let all the oil that possibly got into the cylinders drain past the rings and everything and after work tomorrow I'm going to try and start the truck. This time with all four injectors being new on the passenger side. The problem started with the number one injector sticking open allowing oil to just pass through and not fire the injector. And then from that it went on through to the next injector and then so on and so forth. Apparently stiction is a thing with factory injectors and with people prolonging stuff and then me ending up with the headache of it.

Does the oil pressure gauge on the dash work for just the low pressure or high pressure?

 

[Newby7.3]

My reservoir is full of oil and it still won't start.

 

[Hendy]

I think the oil pressure sensor is located on top of the HPOP reservoir ( I'm not completely sure though)

 

[Hendy]

If you could get some codes that will help us figure out what's going on.

 

[Newby7.3]

Yes it is brand new. And when the truck dies it would take a minute before the oil pressure would build back up.

 

[Newby7.3]

Almost like the low pressure oil pump is going bad. Except for the truck will not start back at all even whenever that reservoir is full.

 

[Hendy]

after the truck dies is the reservoir full? is it a minute of cranking it takes to get the oil pressure back?

 

[Hendy]

I had a similar issue where my truck would take about 30-50 seconds to build oil pressure then it would start trying to start, it ended up being my HPOP

 

[Newby7.3]

When the truck dies I'm not thinking about checking that. But the truck hasn't tried to fire up since I replaced the injectors last night. And before that it died because the air heater kept grounding out and killing the ignition. And now it just won't start back it hasn't started in about a week. But yes it is like it takes about a minute or two of cranking before I see oil pressure.

 

[Newby7.3]

Today I'm going to pull the h-pop off and get it warrantied out with a new one.

 

[Hendy]

I am not completely sure that's your problem though, It could be a bunch of other things, that was just something that happened to me. You could test your HPOP pressure to see if it's bad

 

[Newby7.3]

Before when I had two injectors just stick open and just not let the oil pressure build the ICP was around 340.. would not go higher and would not go any lower.

 

[Newby7.3]

Changed one injector and it would fire up. Next day died. Popped another one. Replaced it fired up. So I replaced the rest and it still won't start.. just here clicking. And no start.

 

[Hendy]

what do you mean by clicking?

 

[Newby7.3]

Sounds like something clicking under the dash. Gets faster as it heats up the glow plugs.
