Fuel Pump Relay Testing
- Remove relay from Power Distribution Center (PDC). Using an ohmmeter, check resistance between relay terminals No. 85 and 86. See Fig 1 . If resistance is 70-80 ohms, go to next step. If resistance is not 70-80 ohms, replace relay.
- Using an ohmmeter, check for continuity between relay terminals No. 30 and 87A. See Fig 1 . If continuity is present, go to n ext step. If continuity is not present, replace relay.
- Using an ohmmeter, check for continuity between relay terminals No. 30 and 87. See Fig 1
. If continuity is not present, go t o next step. If continuity is present, replace relay.CAUTION: During the next test step, if ohmmeter contacts either relay terminal No. 85 or 86 when relay is energized, ohmmeter could be damaged.
- Energize relay using two 16-gauge or smaller jumper wires connecting relay terminal No. 85 to ground and relay terminal No. 86 to battery voltage. Continuity should be present between relay terminals No. 30 and 87. Continuity should not be present between relay terminals No. 30 and 87A. If continuity is not as specified, replace relay. If continuity is as specified, check fuel pump relay circuits and PCM. See TESTS W/CODES - 2.5L article in this section.
