Subject:voltage needed to run an '88 fuel pump?
From:Lee Kouns

Well, I checked the voltage at my silent fuel pump today. When the
ignition was first turned on, I got a maximum reading of 9 volts for a
second or two, but still no sounds from the pump.  When I tried starting
the engine, the voltage went back up to about 9 volts and stayed there.
What's the minimum voltage the fuel pump needs to operate?  Should a
battery in good condition supply more voltage at the pump than what I
got?   Is it time to replace the battery and see what happens, or is
there another test I should try first?
   Any comments are always appreciated.
