While I was towing a trailer down a steep hill the truck abruptly stalled and won't restart. It stalled 2 times before when I was coming to a hard stop but it restarted fine. I just replaced the batteries and fuel filters 150 miles ago. Towed the truck 130 miles home with my 99 7.3! any ideas where to start before I bring it to the dealer. thanks for any help. 05 f 350 w/ 138k on it

 

45 hits and Nobody give a guess ??????????? I know can be BRUTAL if wrong LOL

05 going to take a STAB at it and say HPO problems

maybe a loose wire since it did cut out on a hard stop or whatever

But more than likely a HPO STC Fitting blown out

need to monitor ICP and IPR% for HPO concerns

got any gauges??????????

 

Ipr.......

 

No guages. I have only owned the trucks for 3 weeks now. I have noticed an exhaust smell when the truck is running and not moving or when I initially put the heat on, not sure if that is an additional clue.

 

Just a quick education on what these terms mean, new to this

IPR Inital pressure reading?

What is the HPO etc?

Thanks for all the help!

 

So you have a exhaust smell while sitting in the cab windows up with air on?

We're you using tow haul mode?

Dealer or private seller??

 

The 6.0s run off of high pressure oil the injectors need minimum 500psi at all times just for the truck to even run.

If the ipr is blown it won't regulate oil pressure and the truck will never start.

Let me ask you this, does it have factory OEM oil filter cap? How about a motor craft of fram Part # CH9549 oil filter?

Check this thread out https://www.ford-trucks.com/forums/1...new-owner.html

 

if you can smell exhaust in cab you have exhaust leak in addition to the no start

so you have 2 problems going on here

 

How much fuel do you have in the tank?

 

Thanks for the all the info. The truck has been sitting since sunday tried to crank it again today and no fire. I disconnected the ICP while the key was in the off position and again no luck. I do not have guages so I was going to pull the turbo, check for oil leak around hpop stc fittings etc and probably just replace the IPR. I wanted to clean the turbo viens anyway so, my thought is I should replace the IPR anyway while its out.

Does this make sense? I

Also I do have the stock the oil filter cap. Gonna dump the oil and get a motorcraft filter as well. Anything else I should do as well, while I am in there?

Thanks again

 

Pull the turbo, remove ipr and if that screen is cracked missing or dirty REPLACE the ipr.

Change your oil, the the oil filter cap from ford, pick up the oil filter from them too and let us know how you make out

 

pulled out the IPR. I dont see any screen so I am guessing this very well maybe my problem. I hope this was it!

 

You can start the truck without the turbo in after you install your new IPR

All you have to do is from that metal oil feed line to the turbo have it fed to inside the valve cover....

Atleast you'll know if its the IPR that caused your problem....

After if you have to do the STC fitting(Which now would be a good time since your right there) you wont have to remove the turbo again....

It will take a few crank cycles for it to start again.

 

Sweet I will try that once i get a new one. I think the missing screen is sitting inside the port where the IPR unscrewed from. I can feel something floating around in there with my finger and looked with a mirror looks like a black plastic piece (almost like a peace symbol) Should I grab some needle nose and eaze it out?

 

Yepp. That's exactly it. I would def try to get that piece out.
