Like the other guys have said it takes them a long time to get prime back and going. I cracked a line on each bank and cranked till I had fuel, just to make sure I had all the air out.
so I pulled the return line off my cp3 to see how much fuel was returning I cranked it over and filled up half the bottle so I believe that's why it will not start . bad cp3?
You should be REAL ******* careful doing that with any kind of common rail system. The amount of pressure they produce can be dangerous. Its also messy and in my experience unnecessary.
Was a one man project so I didn't have my face in there. Have only had a couple that required that. But no longer have to worry about duramax :hehe:
