I had to replace several items on my truck 6.0 PSD.
We started with the more easier changeable items, 1st fuel pump inside frame rail (driver side) 2nd Crank NOT___Cam Position Sensor. No Luck .
The Engine turns over but no fuel or to be exact NO oil compression on a (compression ignition engine) . Then the fun part ....not, LOL.
The HPOP along with a multitude of variable size O-rings in different internal locations, This was all done systematically, through pressure leak down TESTS. Finally got her started and am hoping that all issues are behind me NOW..
PS: All this was done with my pvt Mech so it will not show on an OASIS Report.
and Ohhh BTW she is an 06' 6.0L PSD.
I had this problem occur after I had my truck in the Body shop for a Front End Collision, I think something broke internally when I had my fender bender,(no one seriously hurt)
I was able to drive her for about 200 Miles ,mostly Highway, when i just got her out of the body shop and, Then she just up and QUIT ? my (speculation) WAS That something fractured internally from the collision and the O-Rings acted like Band-Aids until the majority of many related system parts finally failed.
I have 57K miles so she was under warr, but I did not want to involve the dealer for reasons stated above amoung other's , another one of these reasons was, that the dealer had a 2 week wait until they could even start to work on my truck.
As far as 6.0's and the dealer, I am convinced that you are more times than not, going to get an unwilling or in experienced tech that will only leave a BIG BLACK mark on your OASIS report and again most likely to cover up and/or not Diagnose / FIX the issues Completely, the first time if at all.
By going my route of CHOICE, If problems persist I have a cleaner History (OASIS) for a potential trade or buyer.
Don't get me wrong I Trully love my Ford and in the 7 & 1/2 months I have had her I have already WON 2 seperate Car Show Trophys...
, BUT IF PROBLEMS PERSIST I regretabll have to say I'll be lookin" HARD at a 5.9L , 24 valve Common Rail Cummins, (unfortunately wrapped in a Dodge). BUT My main concern Like Yours is the FOREMOST need for RELIABILITY. Good Luck and keep us posted.
Prior to the fender bender I had no real engine problems AT ALL, This fact leaves me somewhat confident that the cause of my issues were Collision related and not just coincedental.
