1994 E150 351, low voltage to fuel pump
<HR style="BACKGROUND-COLOR: #d1d1e1; COLOR: #d1d1e1" SIZE=1><!-- / icon and title --><!-- message -->I have a 1994 E150 conversion van with a voltage problem to the fuel pump. I installed a new pump when the original pump suddenly stopped pumping. But then I discovered the voltage to the inertia swith is only 6.2 volts, after the new pump wouldn't run either. I checked the obvious but no solutions yet. Could the ignition swith be the culprit?
I need ideas. Thx

Do you hear the 1-2 second fuel pump prime when you turn the key to the on position ???

Are you infact getting the correct power/voltage to the fuel pump (you stated only that you have 6.2 volts to the inertia switch) ???


More information needed !!!!

Open circuit somewhere. You are measuring a phantom voltage. You need to start at the Fuel Pump relay socket then work your way back through the inertia switch then onto the fuel pump itself.
