Where is the crank shaft sensor for a 2001 ml320 ?

crank shaft or
ckp crank shaft sensor. CKP
broke the connector?

crank shaft sensor transaxle bell housing. oxygen sensor located in the exhaust manifold.

On Multi point fuel injector cars where the sequential actuation of the fuel injectors occur the timing is triggered from the Crank Shaft position sensor.

The cam shaft is an also key sensor providing the crank shaft rotation sequence first or second rotation to provide the complete timing function

Without these two sensors no spark or fuel.

An engine code will be recorded will provide the culprit if one has failed.

Hope this helps.

To turn over or start? I would suggest crank position sensor as it is a reoccuring pproblem which sends no fault to the engine computer.

on top of the crank shaft

If all the fuses are good,replace the crank shaft sensor,this is the problem.

It should be down near the crankshaft pulley. Remove the the right front wheel and the splash shield, it should be there next to the pulley.

this should help.

was the insulation on the wiring harness of your old crank sensor damaged in anyway. if it was damaged then it was also grounded which means you need to check your fuses

replacing the crankshaft sensor might solve the problem.
