Arrggg! I have a 2000 Slk 230 never have had any problems with it before it has 40k miles on it, 5 speed Manual Transmision.

I went out of town for two weeks and came back now the car will not start checked the battery it is at full charge with good clean connections, Put the key in depress the clutch pedal all the way to the floor turn the Key.....Nothing. All the dash lights come on as normal no error codes showing everything in car works however when turn that key the last little bit for the starter nothing. this happend once before but 20 minutes latter it started and has been fine since however it was the same way before it sat for two weeks when it happened. checked all the fuses all fine. I do not hear any relays clicking ( not sure if I should ) however I would think so, The front electric fans come on. Any ideas?
