Hi - I've been trying to get my '72 450SL started for a while now, and was wondering if someone could help please. I am trying to rule out a fuel pump or solenoid fault by disconnecting the fuel line where it joins the rail in the engine bay. I was expecting to see fuel when the ignition is switched on to pressurise the rail, but nothing comes out, even when cranked. I do hear a short 'buzz' from the pump when the ignition is turned on - is this correct please? Should fuel be pumping with the ignition on please?
