also it takes 2-3xs to start ... sounds like it will start and will crank 3 xs then stops ... will start when jumped no problems ... battery is between 12.9-14.2 (thereabouts) ... lots of white smoke eventhough it is out on country roads approx 75miles a weekend at 60mph ... normal short drives during the week ... can it be the high pressure fuel injector pump or oil pump? tank delamanation?
