have a 04 3500 srw 6 spd 4wd that has long crank times. doesnt matter if it hot cold or warm. we reprogramed the ecm as per tsb # 18-033-04, the most current tsb for hard start cold/hot. any info would be much appericated.

could be injectors that are going bad.

 

Had a similar problem with the identical truck. Truck actually stopped and would not restart for 15 plus minutes. In tank pump replaced and problem still not solved. Finally determined it was the fuel rail modulator. Replaced and runs and starts great.

 

tedwhazen: did the truck has any performance issues because this one runs fine and has plenty of power just has the long crank times. was it a fuel rail pressure sensor or fuel rail module because i cant find a fuel rail modulator in my mitchell on demand?!?!
