NOW that I said the truck was running great on B20, I need to mention that yesterday I replaced the transfer pump as the old one failed. After I put the new one on and primed it, the truck ran PERFECTLY. Since it's been cold and I hadn't run it for a couple of days, I let it run about 20 minutes.

THEN, an hour later, I go to start it and nothing. Engine turns over, but it won't start. I figured the new transfer pump was faulty, so I bought one from Cummins. Put it on, no dice! Zippo, nada, goose egg.

A new filter/separator should arrive by mail tomorrow.

Anyone have any ideas? I don't think it's related to the B20...

 

Any chance that your shut down solenoid is faulty or not getting voltage?

 

i would think it be the shut off or air in the lines,

 

Hmm, it could be the shutdown solenoid, but I haven't investigated that. Where is it and how do I check it?

Air in the lines is something I've considered and checked out it seems okay. I guess I could loosen the injectors and try pushing any air out.

The drag is that it's pointing uphill and is parked in the street. I hate working on it in the street!
