Unhappy 300e misfire

My 1989 300e has a serious misfire between 4800-5000 rpm
It misfires in neutral and when driven in automatic or when second or third gear is selected.
New plugs, plug leads,distributor cap,rotor,fuel filter have been fitted . To start the engine it requires that the gas pedal is pumped 3/4 times it will then start in 2-3 seconds and run ok, the problem not occuring until the above revs are reached
It appears like fuel starvation. Have i a problem with fuel pump or delivery pressure ? Any ideas
