Intemittent starting C240 (202) Crankshaft Sensor?

[stargazerplus]

Sometimes the car cranks and does not start. Most of the time it starts first time. There does not seem to be any pattern. It always starts first time when stone cold. First failed to start when parked up for six hours in the daytime. Today failed to start when hot, but fired immediately on second attempt. My guess is the reference sensor (crankshaft position sensor)... what do you guys think? Do you know the part number?

have you changed your battery recently ? i had a problem with mine failing to start,

changed the battery, problem disappeared...

Not a battery problem. I have a battery conditioner and the battery shows a very good charge and 'strong' condition!

Thanks for the suggestion!

how old is your current battery, if theres a duff cell in your battery then the car will start to act strangely (not starting amongst other things)
