Hi everyone, it's happened several times with my 2000 ML 320. The car usually start right up but lately it's cranking but do not start, but if i tried to start and waited for 10-15 mins, the car starts right away. This problem happens again about couple days later, then I have to do the same procedure, and the car will start after 10-15 mins trying. I have heard that this problem may be caused because the crank position sensor is bad, is it true? Please advise, thanks for your inputs.
