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.

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.
