Cool 88 300e 124 Fuel Pump Relay????

Before I change the $113.00 fuelpump relay,I understand there are other things that can cause the relay to shut off the fuel supply. I have taken out the relay and jumped the power pins and the car runs fine no rough idle or stalling when warmed up! but I have sen on other posts that the Idle speed controll unit,a/c compressor controll unit,tach,Cis-e controll unit all can cause the relay to cut out. Any sugestions on further trouble shooting? I have already replaced the fuel filter, coil, plugs, wires, cap, rotor, no help! only removing the fuel pump relay and jumping the pins eliminates the problem!
