started right up this morning,then died,no restart,checked spark,none!!,over the years of owning this truck ive come to discover its USUALLY the crank sensor,and the one in there now is less than 6 months old,so i did a ohm test on the one i replaced last fall,it showed bad,so i ordered a aftermarket one to replace the mopar one i put in last fall,its lots cheaper than oem and has a 36 month warranty,if this dont fix it then DUH!!!,im running out of ammo for the parts cannon,and money also!
