HI y'all. I have a 99 S320 that has been acting up. Battery is good but some times I turn the key and nothing (starter wise, electrical system is up and running fine). If I move the gear shifter to neutral, then try it, it usually starts. But can take up to 10 minutes of trying and sittting and retrying before it actaully starts. Other days, no probelms what so ever. Is there some lock out switch that is stuck or something? Thank you.
