Engine Starter Relay?

CL500 / 2002

My ignition key will hold over in the starting position, which suggests that authority to start has been given, but 9 times out of 10 the sarter motor does not run, so no start. When the starter does turn the engine starts immediately and runs perfectly. Is there a STARTER RELAY somewhere in the fuse boxes that may need replacing?

Could be your crankshaft position sensor is starting to go out.

Must be something else, as I have just changed that and the brake pedal switch.

The point to notice is that the starter moter does not turn at all while the engine is miss- behaving. But that the engine starts well as soon as the starter moter agrees to turn.
And I do have a new fully charged battery.
The car just sits there quietly with the key held in start and nothing happening, then after 4 or 5 attemps it roars into life.
Very strange!

I am also having a similar problem. I have a good car battery and new batteries in the ignition key. Is there a relay that may be the cause?
