well its cold here, so heres a couple cold start videos
ya my 90 even has a bad battery, the 96 has two new battrerys and a new starter and it always has a hell of a time startin below 35 degrees. Itll run rough and blow gray smoke and wont idle then it just clears up all the sudden, it has a mind of its own
I used to drive a newish 94 doge years ago hauling lumber and that thing would never start cold. We had to plug it in when it was 15 or colder. I had a 97 for a while that would not start good with only 80,000 miles on it. The VE trucks have always started much better when very cold.
my 91 starts like yours. if it will turn fast enough it will always start. my 97 starts hard but my timing is way fast. sounds like yours is too. how long has it been still you run the valves.
my uncles 2005 would not start when it was 50 deg unless pluged in and that truck was nothing but junk when new truck only had 40k miles and was on its 2 transmission so he got rid of that and got a 2010 and the transmission went in that at 15k miles good engine junk truck thay need to put the cummins in a better truck
