Hard Starting 90 D250
My 1990 D250 seems to have to work very hard to start in the mornings. It has a brand new Group 31 battery, it only has a single battery, not duals. The grid heater seems to be working, it just acts like the starter has trouble turning it over on cold mornings. Any thoughts? Thanks.

I have 2 92' Cummins, 1-00' Cummins and 1 05' Cummins and my 92's are the most sensitive to the cold. Mine are also single battery but I make sure they are 1,000 cranking amp batteries. They don't like to start when they turn over slow trust me. When it gets below 65 I preheat till the light goes off and then I wait about 5 seconds and preheat a second time and then she cranks right up. If yours kind of runs rough right after you start it that means the cylinders are still cold. The older Fords were notorious for cracking cylinders when this would happen so shut it off and pre heat one more time. Let me know if this changes anything.

mine is the same. it can sit all night or i go on top the mtn and snowboard for about 8 hours where its like 15* colder and come out cycle the heater once and touch the key and it fires right up. in my opinion the electronic trucks take longer to start.
