It sounds like your preheat system is not working properly on the cold startup. Haynes has a Diesel Engine Repair Manual, part #10330 that will help you correctly diagnose and repair.
Battery volts at 13 is good but a fully charged battery should be close to 14.2. It would be a good idea to get the alternator output checked and a load test done on the batteries.
Hope this helps.

This engine 'loves' glow plugs! One goes and the others try to handle the amps. Change them and you will have no probs! Other than that, I feel this is about the best diesel truck made!

7.3 rough idle


Gas or diesel having same problem, I'd start there to confirm fuel pressure . It may be pump running partially when cool, but when it heats up (the pump) it may be cutting out pressure wise. Not uncommon for a fuel pump to pump good when cold, then die once pump heats up from running. Still makes noise, but isn't supplying any or enough pressure.

We think it is the diesel injection pump but not sure


Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day
