Need help
ok heres the problem when the temp gets below 40 truck will not start, unless I unhook all 4 cables then it will fire up after that as long as I plug it in when the truck is warm it will start the following morning. I already took it to a shop he tested all my injectors cascade valve injector pump and lift pump done a flow back test everything passed, all he found was a update on my pcm took it to dodge they said there was a update for long crank time during cold weather temp updated it and said give it a try. this morning temp is around 39 would not start once angina unhook cables for 20 min and its fires up.
