I am positive it is the stater i hear spinning, i marked the cooling fan with a pen to see if it would move when I turned the key and it did not, the engine is not turning. If the starter is spinning when i hit the key i am pretty sure its getting voltage. I don't hear any clunking, clicking or grinding. The only thing that i can think of is that maybe i reversed the polarity of the wires connected to the solenoid. But I could not have done the either because the post are different sizes! I remember bitching about it taking it apart. I have pics Im a post one
