FUEL DELIVERY
Fuel Pump Relay
1. Remove fuel pump relay from power distribution center at driver's side front corner of engine
compartment, near the battery. Note terminal identification on fuel pump relay. See Fig. 5 .
2. To check fuel pump relay resistance, use ohmmeter and check resistance between terminals
No. 85 and 86 on fuel pump relay. Replace fuel pump relay if resistance is not 70-80 ohms.
3. To check fuel pump relay operation, connect ohmmeter between terminals No. 30 and 87A on
fuel pump relay. See Fig. 5 . Ohmmeter should indicate continuity between terminals No. 30
and 87A on fuel pump relay.
4. Connect ohmmeter between terminals No. 30 and 87 on fuel pump relay. See Fig. 5 .
Ohmmeter should indicate no continuity between terminals No. 30 and 87 on fuel pump relay.
5. Connect 16-gauge jumper wire between negative battery terminal and terminal No. 85 on fuel
pump relay. Connect 16-gauge jumper wire between positive battery terminal and terminal No.
86 on fuel pump relay.
6. Continuity should now exist between terminals No. 30 and 87 on fuel pump relay. No
continuity should now exist between terminals No. 30 and 87A on fuel pump relay. Disconnect
jumper wires. Replace fuel pump relay if defective.
7. If fuel pump relay or wiring circuit failure exists, a Diagnostic Trouble Code (DTC) will be
stored in Powertrain Control Module (PCM). See TESTS W/CODES article.
NOTE:
For fuel system pressure testing, see BASIC TESTING article.
