Any fault codes stored? Check that first.

This forum is dedicated to the W124 chassis 500E and E500 with M119 engine. Your 2003 E500 is a W211 chassis with M113 engine, two generations newer... there may not be many people here who can assist.

Got spark?

And do you have some sort of scanner to check for fault codes? Almost impossible to properly troubleshoot this without a scanner or SDS/DAS.
