I know a guy with an '03 6.0 that's having issues with shutting off, typically on the highway. I don't think its a HPO issue.
He just had a new oil cooler, egr delete, new standpipes, and 8 new injectors installed. He told me that it was having the stalling issue prior to the repair and was told by his mechanic that it was a HPO leak.
He says it's still stalling out of the blue 3-4 times a day on the highway, seems to be ok in town. His FICM reads 40v which is not ideal but doesn't seem to be causing any hard start issues yet.
I told him to read the codes next time it dies. He called me today and said the truck threw 13 codes. I don't know what all of them were but he's getting codes for all 8 injectors and a codes for an open circuit.
I don't know exactly what all the codes were but from his description it leads me to believe that:
1: He needs a new FICM
2: He has some possible wire chaffing causing short circuits?
Am I on the right track here? Will short circuiting cause the truck to die out of the blue like that?
EDIT: forgot to add that the truck will fire right back up after it dies.
