5.
Measure the voltage at the terminals of the fuse box which correspond to terminal 30 and 86 of the fuel pump relay.
^
The correct measurement should be battery voltage.
If the correct measurement is not obtained, repair the power supply to the fuel pump relay. Refer to CHASSIS ELECTRICAL DIAGRAMS.
6.
Reinstall the fuel pump relay.
7.
With the key still "ON", measure the voltage at terminal 87 of the fuel pump relay.
^
The correct measurement should be battery voltage.
If the correct measurement is not obtained, verify that the circuit to ground from terminal 85 of the fuel pump relay has continuity (less than 0.5
ohms resistance).
If the circuit is OK replace the fuel pump relay.
