Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. If the engine is cranking over and the vehicle is just not starting then it may be a failed fuel pump or possibly a crank sensor problem. If it is not cranking it can be an electrical issue as it sounds like you have enough voltage for it to crank over. Do you have a scan tool to see if there are any codes in the computer?
If you have a fuel pressure tester you can test the pressure at the fuel line under the hood. Or if you listen closely to the fuel tank see if you can hear any noise from the pump when the key is first turned on. If not then the pump may be bad.
It is located inside of the fuel tank. The fuel tank is located underneath the car. You should have an access panel under the rear seat to more easily get to it.
