Biodiesel Cold Start Trouble
been running b99 for the summer no trouble. This am 32 degrees and no start. Pulled fuel filter added regular diesel purged air from the system and put 10 gal of regular diesel from the bobcat into the tank to make a 50 50 blend. I've cranked it enough times to get some white smoke out of the tail pipe but it wont stay running. Feathered the gas pump to keep it running for about 1 minute. I've had it plugged in for 6 hours now and the fuel feels warm in the filter. Have I drained the batteries to the point where the crank speed just isn't enough? or is there a chance I burned out the fuel pump with the more viscous fuel?

The pump is pretty robust, I wouldn't replace it just yet. Have you tried jumping it yet? The Super duty is very dependant on strong batteries both for starting and for the glowplugs.

Just got back from jumping it. Spun faster, but still nothing. Any chance the engine is full of cold fuel? I saw that on some other threads. If so any way to purge it. It was catching at times with a pronounced knock, but now it just cranks

purge fuel lines?
Got new batteries so the crank is real strong. The biodiesel is from Twin Cities Biodiesel. Have not had a problem in two years, but I tend to switch end of September to regular fuel in MN. How does one purge the fuel lines

Moral if this repair is keep it simple. Why did it stop? Too cold. Cranked the heater in the shop up all the way. The ford outside temp guage read 100! Sat in there for 5 hours. Went out and it started like nothing was wrong. Done with Biodiesel for the season in Minnesota. Thanks everyone
