Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi, welcome to Just Answer. My name is Marty.
Your car has an automatic starting system. The computer will continue to operate the starter for 8 seconds in an attempt to start the motor. If the motor is not starting there is a problem with the fuel or ignition systems.
The most common problems are a faulty crankshaft position sensor or a faulty fuel pump. There are many other possibilities but those are the two most common.
You will need to have a technician test the ignition system and fuel system to pinpoint the problem.
