Alright I've told the story before. In March the truck got new injectors installed, $3700 later the truck still wouldn't start so the guy sold it not running.
Next owner buys it and puts a new CP3 pump on it, but it still won't fire up on it's own and fuel system won't hold a prime.
So, I bought it last week. On the advice of a friend that works on diesels he said replace both lines off the fuel filter housing with clear tubing(temporary) to see if I'm getting air before or after the filter housing. There were no bubbles from the FICM to the filter housing, but there was a constant flow of bubbles from the housing to the CP3. Sooo, I thought the housing was cracked so I ordered a brand new one with new everything attached to it. I installed it and pumped the primer and it got nice and hard and held a prime. We every time you spin it over it looses prime. I got it to fire of a small squirt of WD40 and now there was bubble from the FICM to the housing!!! So I went to the dealer and got new washers for the banjo bolts and installed those and it seemed to fix that issue but now I've got bubbles from the housing to the CP3 again.
With the truck running should diesel completely fill the hoses at idle? Reason I ask is neither hose completely fills with diesel but they both flow fuel constantly while running. I'm out of ideas without taking it to a shop and leaving it with them.
