driving home from my hunting trip my truck started sumbeling and loosing power till it died. i tried to restart it but wouldnt work til i let it sit for about 10 min. continued trying to drive home but then it did it again. once more 10 min later it started back up and died again just a few miles down the road. now it is completly dead. turns over just fine but nothing happens. its a 2003 6.0 and is stock. i just replaced the icp sensor and have a leaky egr cooler. i just ordered the egr delete kit yesterday. im not real familiar with deisels but it kinda seems like a head gasket. my wife said when it started back up there was a lot of white smoke. any help would be apreciated

 

1. How about some details about your vehicle, model, year, engine, mods, mileage.

2. Check tech folder.

 

Is it getting fuel? Remove cap on secondary FF housing and see if theres fuel in it. If no, possibly HPOP. How long since you changed FF's? Maybe fuel gelled? Whats the temp? Are you using anti-gel if it's cold? Theres a thread in the tech folder near the top from Bismic about diagnosing a no-start condition. Keep us posted.

 

Loss of power followed by a stall then a cool down and restart sounds to me like HPO leak.The EGR leak is it leaking onto the motor or into the motor?If it is a leak into the intake have that sorted first as it can also cause driveability issues and serious engine damage.

 

I was thinking HPO but mine died and wouldn't restart. Agreed with leaking EGR cooler!

 

the truck is a 2003 f250 with the 6.0 L it has 94000 miles on it and is completly stock. the temp outside is around 16 degrees and i do use a anti gelling adative. i have never replaced the ff was actualy planning on doing it next week. the egr as far as i know is leaking onto the engine and not into it. i will check out the tech folder and thanks for the help. and just out of curiosity what is the hpo

 

HPO is high pressure oil that is used to fire the injectors.

 

so i pulled the cap off the secondary fuel filter and there was no fuel in it. could that be casued by a fuel pump not working.

 

My vote is the HPOP STC fitting failure.

 

is there anyway i can check that and what excactly does it do.im trying to learn and fix at the same time

 

derrek...here are a couple of article from Diesel Tech Society...I'm personally aware of the symptoms, but not sure how to diagnose...took it to the dealer and it was replaced under warranty.

there's a fuel delivery problem obviously.. check to see if the pump runs at all(it's under the drivers seat on the frame rail)..turn the key on, without starting the engine, and the pump will run for about 20 secs before the computer commands it off.. also, fuel filters could be dirty and the fuel is too thick to pass through...the fact that it was running and died doesn't lend itself to a fuel quality problem though..

 

Fueling is a simple issue to solve.Your injectors will not like what just happened.

 

check fuel pressue sonds like adead fuel pump. icp should be good if its puffing white smoke. you need 500 psi to try and light the engine off. so we know its got that.

 

so are there speacial tools required to check the fuel pressure. i have a standard fuel pressure guage for use on a gas car are they the same.
