Have you checked the glowplug relay.

Make sure your plug wires are not being affected (brittle, old,etc}. An engine oil heater works well in cold areas. Possible thickening of oil.

This engine 'loves' glow plugs! One goes and the others try to handle the amps. Change them and you will have no probs! Other than that, I feel this is about the best diesel truck made!

Diesels are famous for hard start when cold. Consider having a diesel shop install an engine heater.

Charge the batteries. take a Reading to make sure that you are getting almost 14v to both batteries. If it is not charging then take the alternator back off and have them check it. you might have bought a bad one. There is a way to test the glow plus with out taking them out. ( Take a piece of wire long enough to reach all the glow plugs from the battery. unplug the glow plug wire.If you touch the end of the glow plug with the hot wire it should make a little spark. if no spark then the glow plug is bad. do this to each one, but one at a time)

It is possible that some of the glow plugs might not be working. This will cause a hard start and smoking condition especially in cold weather.

Have you checked your glow plugs? There are a number of additives you can use. Go to Amsoil.com and try some cold start. I sell this stuff and alot of other things for diesels. I invested in a small code reader from my local auto parts store to help me diagnose my truck.

Yes, my 2003 did the same with about 75k miles on it, stranded me on days it stayed under 40F unless I plugged in the block heater the night before, then it started like a champ. Dealer replaced the relay and a control unit under ESP warranty. There's no way to fix this one without throwing parts at it.
