Just replaced neutral safety switch on my 560 sel and it still would not start. so i replaced the starter- you can bypass the safety switch and it will start but the starter stays engaged. I am a bit stumped on what else to look at. Only had this car a short while so not familiar with this model. i had a 380 sel and barely had any trouble out of it> NOt a mechanic obviously- just a chiropractor trying to fix my favorite ride! What else do i try?
