will not start without being plugged in

my 2000 7.3 will not start without being plugged in (120v heater). I had the glow plugs system checked out and all was well. Is there another sensor that I might be missing? Garage that check it out said I might need a new computer, if so is the dealer the way to go on that?
Thanks

Are the glow plugs not energizing, leading them to think it needs a new PCM?

No they are energizing, can't understand why it won't start with glow plug system working but will if engine is warm from heater.

How many miles is on it? I don't see how they could assume it needs a new PCM. If it does run the PCM is probably fine. Are they the ones that checked the glow plug system also?

Pipelayer they are the same, honest shop tho. The truck has 250,000 miles on it. When he pulled the codes on it he found two that indicated a faulty PCM.

Doesn't make sense to me as you need the pcm to start the truck whether its plugged in or not.

I had the same thing going a couple of winters ago. My truck wouldn't fire up even when 50+ degrees. I had to plug it in all the time. I changed the Glow Plug Controller and that solved the issue. Mine didn't throw any codes when it happened, and if it weren't for this website, I may still be plugging my truck in every night.

I would say check you glow plug relay etc.. and also check your battery cables. I just had a similar problem with mine and it was a bad battery cable.
