Fuel pump issue
 

Drove my c320 Thursday, Friday morning it wouldn't start. Would try to start for 10 sec, would turn over then shut off. Thought check fuses, replaced fuel pump relay,hooked fuel pump to battery and the fuel pump runs. But no power to the fuel pump at the connection. Where should I look next?

Hello and welcome to the forum! I would suggest pulling the codes - this should give you a definitive answer as to where the issues and coming from.
