Re: What works to start a cold diesel engine??
in my limited diesels it is best to set up a block heater on a timer like lapeer20m was talking about. atleast use some sort of means for heating. i've seen diesels refuse to start on 90 degree days without ether when it was used too much previously. if you do have to use it it is best to only use it sparingly so you don't run into this trouble in the future. although of all my friends who have had diesel trucks the cummins' were always the best about starting cold. the ones that had trouble were typically gm6.2 &6.5 or early ford-navistars (6.9-7.3 idi).
unfortunately i fell off the bus. and now i'm not even near the darn road! ;) ;)
