OT cummins help

[pieceofjunk]

I have a 93 Dodge 250 with a 12 valve cummins. I replaced an injector and now it will not start. I have tried to bleed it out numerous times, but it seems like it isnt getting much if any fuel through the injection lines. If I unhook all the lines from the injectors and crank it over I only see maybe a drop of fuel come out every once in a while. Do I still have air somewhere? What things should I check for?

don't know much about the 12 valves, I have a 24 myself. Did the IP a year ago. How is the fuel filter? Are you getting fuel to the filter canister? I would check there first to determine why you are getting just a dribble. Then make sure you crank on it for a while to get all the air out. I remember cranking for 30 seconds then stop then again until she fires. The close the lines off as she smoothes out. Like I said, not totally familiar with the 12 valves, don't know what kind of lift pump they use. But that is what I did.

Neighbor had one that the fuel line was rusted out and it sucked air. Maybe worth a check of the lines as that is pretty old.

Try www.turbodieselregister.com - they have a section for 12V engines. It's a good site for Cummins owners.
