W203 no. Start

[Jamdog]

Hi I have a c200 on a y plate, had for two year and never a fault, now I can't start it and I'm confused as what's up, many posts point to poss battery some ecu and some gear selector. Car has full dash lights on and releases staring lock, but that's it, no click and no start . Also ( didn't notice at first) now stuck I. P can manually release using mech release, does this point to the gear selector unit? And if so can I get a s/h one??

You do have the starter lock out switch on the selector. Welcome to the forum.

Could be circuit 87 relay in front Sam. This is a common issue along with a few other possibilities
