Hi there. If you tested the fuel pump and noticed that it was not "humming" that's either an indication of a fuel pump electrical relay (as you suggested) or a fuse that is broken. It could also indicate that the fuel pump is faulty or that the ground wire attached to the fuel pump has become loose. I'd check those three items first for electrical continuity. If you still can't get the fuel pump to work, contact a professional mechanic to complete a fuel pump is not working inspection, so they can pinpoint the source of your MB's engine issues.
