[AJD] 2 cyl diesel won't start

Wed Jun 13 01:24:21 PDT 2012

I think it's probably low cranking speed. Or possibly it just needs air bled 
out of the system. I doubt it's bad fuel, as I've had diesels sit for years 
and fire right up with no problem at all on the same fuel.

My first thought is to try just pull starting it, to get it running, get the 
oil circulated, etc.

After you're sure it will run, try the electric start again.

Was it converted before it sat? I mean, was it starting with your current 
setup before you finished the restoration?
