Hi all Had a cam pulley break a while back and snaped the rocker arms. Rebuilt it yesterday but no start. cam timing is spot on i checked it about twenty times. It will run with easy start until the vapor is gone. It seems like pump timing is out but it is set right. can any body give me any thing else to look for. There is great pressure at the injectors it sprays about 10 foot in tha air when i crack open the pipes. Also i do not have the aux belts on could this be the problem,i had an old volvo years back that would not run without the fan belt. thank you in advance. dave king **** left the pump locking pin in now i just cracked the pump,have another casing though.
