This is from the Powertrain Control Module (PCM) pin 9 of the Green connector, a Dark Green/White wire. 3. One terminal should be a good ground to G102 and the other terminal should have continuity to the pump. Putting 12 volts on the pump terminal should show 12 volts at the pump with the pump plugged in. If the voltage is low at the pump there is a wire problem between the relay and pump, inspect the connections under the under hood fuse block. 4. Verify the pump ground is good and the ... read more
