I started my H2 and it started fine, no hesitation at all. As I began driving up my street, it felt sluggish and then died. After it died, I tried turning the key over, I can hear the click, but it doesnt want to engage the starter. I have no indication what gear I am in - so I am wondering if it could be the Transmission Range sensor and if so, how do I replace it? Where is it located? What is the procedure?
