Hey guys, so first off I got referred to this forum from one of my buddies who said you guys were a really good bunch of informative and friendly people who don't mind helping.
So I bought my first diesel truck September of last year a 2006 Ford F350 Lariat w/ the 6.0L Powerstroke and drove it about everyday and loved every bit of it, and only recently with the really warm weather here that it started having issues. when I bought the truck it had about 72xxx miles and now just under the 100k mark.
Long story short, one day I go do errands all around town and have to fill up. Fill the tank, pay, get back in the truck and crank for a good 10 seconds before firing up. Didn't really think too much about it, figured it was a hot and humid day everything is working twice as hard. Then a week later I go to start it and it takes a good 10 seconds to start up, idles about at 300rpm and dies flat on its face. Tried it again and it started up like a champ, like nothing was wrong... then today I just filled the tank up and it wont start just cranks over with no start. Sitting at the pump for a good 10 minutes before I try again and it fires up no issues.
Check around the net, called a few of my mechanic buddies, and some tell me of the FICM going bad, got home checked the FICM when its cold, 48v and 47v cranking, so not the FICM, checked around a bit more then one of my buddies tells me of either the HPOP or the O-ring on one of the injectors (dummy injector?).
Now I did some research on this board and a few others and found a lot of answers for the HPOP and STC fitting, and keeps bringing me to these videos of how to easily replace the STC fitting on the HPOP, cool I'm pretty mechanicly inclined and can probably knock this out in a day.
But there seems to be little information on the O-ring that keeps coming up, and with my luck, that's gonna be the issue, so basically I'm asking for any of the 6.0L gurus out there for their opinion and help for this diesel newbie get his workhorse running properly again.
Any help is greatly appreciated. Here are some of the stats on the truck:
- 2006 F360 w/ 6.0L Powerstroke
- All Stock
- just under 100k miles
- Runs great when it starts but will occasional fall flat on it's face 2 seconds after starting
- When it won't start the engine is still warm around operating temp.
- Occasionally will be stopped at a red light and the idle will drop to ~500rpm and pick itself back up to ~700 and even out at 680ish
- Stalled while driving once or twice but started right up again
- Some days will take a lot of cranking but will start at 200rpm and slowly make its way to 650rpm
- No black smoke whatsoever
Thanks in advance.
