Disconnect the electrical connector from the pump. The resistance test is done at the electrical harness connector, (not the pump). Set the meter to ohms, touch one probe to the black wire termianl and the other test probe to a good, clean chassis ground. There are 2 black wires in the harness connector, check both of them. Resistance must be less than 5 ohms on both wires.

To test for voltage at the pump, set the meter to volts. Touch one probe to the grey wire and the other probe to a good, clean chassis ground. Must show battery voltage for 2 seconds when you turn the key on. After 2 seconds, voltage should drop to zero volts.
