c280 2006 and a c300 2010
c280 2006 won't start

Hello everyone I'd like to thank everyone in advance for the help and input.
My c280 2006 with 140k km shut down at a red light and won't start again. I get a crank no start and don't suspect it being a key problem. The fuel pump, spark plugs, starter and computer have been changed. Atp I have absolutely no idea what the problem might be. Battery has been checked and gives good voltage as well. Any help is massively appreciated! The mechanic also told me he did a compression test and all was well so I do not suspect engine failure or timing chain issues since the mechanic also told me it isn't the issue.

Does the fuel pump turn on for a few seconds when you turn the key to the run position. Is the security light on? If you have fuel and no spark the first suspect is the crankshaft sensor. The engine will not run if it's bad.
