I just joined this forum to see if I could get some help and discussion on the 6.2 liter GM Diesel. I am at the end of my rope as far as what I know to do and I have already seen a few helpful posts here. I was driving it down the road and it just died! I havent been able to get it to run again since. It was very cold so I assumed that the fuel gelled up....So far I am still stumped. I replaced the fuel filters, bled the air out of the system and checked the glow plugs and it wont hit a lick?
