Ok guys i had this cold start issue since i've had the truck.
I have changed th pcm altenator, glow plugs, glowplug relay module(CA part not a solenoid), injector o-rings, injector cups, oil temp sensor, and batteries. last scan run a couple months ago had no issues come up.
If the truck sits long enough to completely cool down no matter what the outside temp is at night (can be 20 -70 degrees dont matter), the truck wont start in the morning, if it does start it runs rough with little power.
After the intial start in the day its fine. To completely get it running smooth i get on it and the rough engine nock stops(minor black smoke), runs fine then.
CHECK THIS OUT====> If i plug the block heater in for an hour the truck will fire up with no issues at all (20 - 70 degrees), it runs smooth.
I am maybe thinking an injector, maybe the one that had the cracked injector cup!
Any Ideas i am stumped with this one.
