....first off the fuel pump needs a MIN. of 12.6 volts to power the main and fuel pump relays, and ignition. Battery boosting
the battery with too high amperage jumper can blow some over-load(voltage) protection relays. The ago old tapping on the fuel pump
is always an alternative.

and your one year old gas will cause difficult starting and poor running

Mercedes-Benz factory repair manuals are available on CD from
any dealer or 10's of online vendors - time to invest maybe
