Our Merc C240 will not crank over at all. Battery is fine as everything else works, voltage tests fine and will not start with a jumper battery either.
It was running rough earlier so I put a scanner on it. It showed a Crank sensor code. I have a new sensor and I'll be installing it hopefully tonight, if I can get to it.
Question is, wouldn't the engine crank over at least, if it is just a crank position sensor problem?
If the sensor has failed completely, can that prevent the car from even turning over?
