Truck turns over and wont start
I have replaced gow plug relay module. That didnt work. Wait light comes on for 1 second and goes out and it seems the glow plug relay then short cycles. The truck turns over but acts llike the batteries are dead. I checked batteries, alternator, & starter. Also checked main fuses and all are ok.

I throw a test light on the plugs to make sure they are good. What about your battery cables, worn, corroded cables will cause a slow cranking issue. How old are you batteries and what is the CA rating of them? The batteries in my truck tested good and were 800CA each and I thought the truck started ok. Putting in two new 1000CA batteries made a ton of difference though.
