ml430 won't start sometimes

On a hot day after sitting in the sun my 430 won't start. When cool starts right up. Any clues?

most likely its going to your crank sensor, if you turn key to position 0 after no start you will clear fault code, leave in position 2 for diagnostics, we also can watch in "actual values" the rpm, 200-300 normal reading, bad crank sensor 0 rpm. we have seen hot weather to be the case on numerous occasions, but not always
