2005 F350, 6.0, Crank, No Start

[killacal]

Hi,

As I was leaving work today I started the truck up, back out of my spot, put it in drive and took off kind of quickly. I big smoke cloud came out of the stacks... then the truck stalled, and wouldn't start.

Thanks to a quick search of powerstroke on my phone, I tried the following:

1) Tried to start with ICP unplugged- no change, didn't start.
2)Tried to start with the EGR valve unplugged, didn't start.
3) Scanned for codes with my SCT, not DTCs present.
**Update 7/25***
4)Check fuses under dash, nothing is blown, all seems well.
5) back probed the ICP pressure sensor while cranking. KOEO I saw ~ .25 V, when I started to crank it ramped up to a .32V. Sounds like a I have an injector pressure issue.

During cranking I looked at the stacks, no smoke was seen. I also check the oil pressure gauge on the dash, it was registering pressure as I was cranking.

I'm not sure where to go from here.... but I'm now left without a vehicle (my backup vehicle's fuel pump died Sunday night).

Any advice, tips, checks, etc...?

This is for the 2005, F350 in my signature. I have 3/4 tank of fuel, and ~ 96k miles.

Thanks in advance.

***UPDATE, Problem Solved****

After replacing the SCT Fitting, then the Standpipes/Dummy Plugs, then the IPR it started. The IPR was junk.

Same thing happened to me when My IPR died

I assume IPR stands for injector pump relay? Is this something I can check easily?

I had the same experience with my 06. Luckily it was still under warranty and Ford sent a rollback to get it from my house and fixed it up. The only thing I would add is to say the oil pressure gauge on the dash will read normal at 3 psi so you really can't go by that. I would check the oil level in the HPOP if it was me.

No it's the regulator for the injector oil pressure rail... It's located on the back end of the lifter valley & plugs into the high pressure oil pump.

If its failed like mine was, you can only tell by checking the ICP via scan tool. If cranking pressure is <500psi the injectors aren't going to put out.

Thanks, I'm reading through several posts as I check this, and I'm going to start by looking at the ICP pressure using the back probe method at the pressure sensor in the valve cover(.84 +V while cranking = good). If that doesn't work I'll have to track someone down with a scan tool... which will be tough.

If ICP pressure is <500psi it's the ipr, hpop, or a decent sized leak in the high pressure oil system... Usually a dummy plug. My ipr failed/stuck beyond cranking pressure. I had just released the fuel pedal coming off the highway and it never stopped at idle speed, went from 1900rpm to dead and wouldnt crank. Since it was down i put in studs injectors and new head gaskets :-/

Hmmm... that sounds pretty much like what happened to me.

I'm still trying to find a writeup on the install, but from what I know it sounds like I'll be taking the top end of the engine apart.

Yea mine already had complete egr delete. Wouldnt be a bad idea to do an oil cooler rebuild while youre in there if you haven't already.
