If you're getting white smoke out the tail pipe while cranking, try shorting the 2 big posts on the GPR with a screwdriver for 30 seconds, then try starting.
The belt not turning does not sound good. Maybe he's got he wrong size belt on there? If the belt doesn't turn, then the alternator is not charging the batteries properly. If the voltage gets too low, the IDM won't fire the injectors as Jim said.

Place the screwdriver across the 2 big posts (one is covered with a rubber boot in this pic) with the key off. Then get in and turn the key all the way to start like it was a gasser (ignore the wait to start light).

It means it's time to replace the GPR. That relay is what sends power to the glow plugs. If the relay is bad, it's like starting the truck with no glow plugs at all. The screwdriver trick simply bypasses the relay and sends power to the glow plugs through the shaft of the screwdriver.

How cold is it outside there? Was there any starting or stalling problems before you worked on the starter? You may have other issues going on here.
The belt not moving still concerns me, but leaving the jumper cables on won't hurt anything, and the PCM will command the glow plugs on for up to 120 seconds depending on conditions, so leaving the screwdriver on a little longer won't hurt anything. Maybe try holding it on for a minute and see how that does.

Guzzle has a nice write up, I would replace it with the Stancor GPR, I just ordered on as the original one just kicked the bucket. 44.79 is what your looking at, and at the price it's well worth it.
