04.5 Cummins Hesitates off idle/Hard to Start
Started fine last winter. Was starting fine till one cold (5 degrees F) morning 10 days ago I had to try and start a number of times till it finally started. Did the same thing today at 30 degree F. After driving for 5 minutes, it will start normally after shutting off.
Hesitation off idle seemed to start day of first hard starting. (every time I start up from a stop) After driving for 20 minutes or so when engine has been at normal operation temperature for 10 min., will drive normally.
Drivers manual is in truck, but I seem to remember it says that on cold mornings you turn key and allow grid to warm up, then turn off and warm up again before starting. Tried that this morning, but light indicating warm up does not seem to come on a second time.
Help appreciated.

Didn't pull the filter yet, but added "Howe's Lubricator Diesel Treat" (found at Farm and Fleet in Racine, WI) at about 4 times the recommended level for cleaning fuel system. Drove 50 miles. This morning started right up and no hesitation even when pulling out of driveway. It as about 4 degree's warmer today, but I'm pretty sure the treatment cleaned something up. Will be changing filter when weather moderates. Thanks for the suggestions leading to the fuel.
