It could but you would get random low circuit codes too. Have you checked for excessive fuel aeration?

No I haven't. How would I accurately check that? I had just filled up and 10 miles down the road the problem started.

 

Bad copper washers will allow combustion gas into the fuel system and then aerate throughout the system taking out injectors.

Gotcha. So no more testing until I have the new oring kits.

 

Bad fuel?

It is a fuel station I have used many times. Also a friend of mine continuously fills up at the same station. He has a dodge, but he has not had any issues. Very frustrating dealing with the 6.0 I much prefer the 7.3's I've had in the past. Only time the hood was up on them was to change oil and top up washer fluid!
The 6.0...not so much!

 

Blaming the 6.0 because you removed injectors and re-installed without new crush washers or o-rings?

Josh

 

No..because I've put more money into 1 6.0 than into the previous 5 7.3 combined!

 

Also, if it were aeration would that cause it to not start when its warmed up? Acts more like an oil leak in the high pressure side. No injectors have any deterioration of the oring from a leaking rail.

 

So today I changed injector one out with injector 7. The imbalance code shifted to injector 7. However, it still would not restart after getting warm. HPOP pressure is around 350psi when cranking when hot. I assume since before I pulled any injectors I didn't have this problem It must be a bad o-ring between the injector and the oil rail.

So is it possible that the seal is bad on the injector with the imbalance (which isn't there cold) and that replacing that seal (well all on that side) could quite likely fix the problem with the imbalance too?

 

I hate 7.3's. Biggest pos out there.

 

You may have a HPO Leak if the IPR% was 28% and Truck was EOT Above 185*f

PLUS those washers need chnge



Sounds like the Diagnostic was Corupt That always costs extra
