It was running before, very rough, stalling intermitenly . I've been wanting to do the glow plugs for a while and it just made sense the replace the vc gaskets. The fuel pump needed replaced. It was leaking from the weepphole. I went out this am. And bled the air from hpo system. Hpop is full. I put a little goofy gauge on the fuel Schrader valve. It slowly built to 15 psi before fuel sprayed out of the top of it... I don't trust it fully... I've tried starting it with the icp unplugged, cel light is automatically on and stays on... Still no start..... I don't have any scanners or anything and I'm not spending hundreds of dollars on one... The other cel light only comes on only while cranking until oil pressure builds... Then it won't come on any more.... Only an expensive snap on type scanner I think would figure that out... Those cost more than my trucks worth so to hell with that
