it didnt start before so i read that the crankshaft sensor was the problem so i changed it and it worked fine that was about a month ago then last night it did it again but this time it cut off going down the road had to get towed and as i was waiting i tryed to crank after the engin cooled about a hr after still nothing so i changed the camshaft sensor today still nothing batt. was checked and is good, could the crankshaft sensor had gone bad in a months time? or is there something else i need to look at?
