Check the oil level in the HPOP. Also need to scan it for codes anyway.

ok i may sound like an idiot but iam new to diesels in pickups what and where is the hpop? my buddy is bringing his scanner over tommorow.

HPOP is the high pressure oil pump. It pumps oil under pressure to fire the injectors. It's on top toward the front of the engine.

I will check that in the am thanks for the help. What if it is low
:humm:

15w-40 diesel engine oil. :tu:

You'll find out more when you scan for codes to, hopefully.

6.0 HPOP is on the back of the engine, passenger side, under or just behind the turbo. I'm not all that 6.0 savy, but I don't think a 6.0 has an HPOP res to refill, it feeds dirrectly off the LPOP. As opposed to the 7.3 usin an HPOP reservior that is maintained by the LPOP.

Are you gettin fuel to the engine? A 7.3 won't throw codes when the lift pump quits, I don't think a 6.0 will either. Disconnect a line somewhere away from electrical and crank it over, you should get a good spray.

scanner wont link up the fuse to the dlc is good and powers scanner just wont communicate properly. I have fuel to the filter on the top of the motor and it pressures up. :argh:

FIMC/PCM possibly, if you can't communicate and you're gettin power to the scanner.

You lost something electronic.

thats what iam thinkin:scare2::ouch:
