Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Pump Relay
Remove fuel pump relay (located near heater duct under carpet). Using a fused jumper wire, apply 12 volts to relay terminal "B." Connect terminal "A" to ground. See Fig 1 . Measure voltage between terminal "C" and ground, while individually grounding terminals "D" and "E". Verify voltage is as specified. See FUEL PUMP RELAY SPECIFICATIONS table. If voltage is not as specified, replace relay.
| Terminal "D" | Terminal "E" | Terminal "C" Voltage |
|---|---|---|
| Open | Open | Less Than One |
| Grounded | Open | Greater Than 10 |
| Open | Grounded | Less Than 10 |
| Grounded | Grounded | Greater Than 10 |
