Cranking
Hi all,
This is my first diesel winter. Around here, it has been about 35 degrees F lately. So, most of the time that its around 30 degrees, I'll plug it in for a few hours before starting and cycle the glowplugs twice. But, I have noticed that the engine cranks slower when starting in the winter than in the summer. It cranks slow a few times, then speeds up and starts. I know this is hard to describe, but how fast should it crank? Do I have bad batteries?
Thanks,
Jack

What Rick said. The glow plugs pull a lot of juice for winter starts. Plus, cycling the glowplugs do not help other than wear down the glow plug relay and batteries. Check your battery connections as well. Just a little corrosion can weaken your system.

Is your engine heater working? Ohm check it.. should be around 40 ohms on the plug lugs. Also, switching to synthetic oil would help.. I use rotella 5w40 year around. Engine loves it..

Jack check your battery connections to make sure they are tight.. every year, come this time, I have to retighten my connections. Once you start turning over, you cause a load, this causes heat, heat causes expansion, expansion causes better connection, turns over better.. Check your connections. At least that has been my story.
