2007 S550 Hard Starting
Thanks in advance. I own a 2007 S550 with 155k miles. It has push button start. Lately, when I push the button, she will crank for about 3 or 4 seconds then stop without starting. Do it again and she fires up. Not immediately but after a few cranks. However, sometimes it will start and die out. But, then other times it fires up immediately. This started about a week ago. Prior to that, 1 quick push of the button and she started.
Any ideas?
Advice would really be appreciated.
Thank you.
