Fuel Pump Resistance & Operation
- Remove second seat, scuff plate, step plate, floor mats and cover plate on floor panel for access to electrical connector at fuel pump. Disconnect electrical connector for fuel pump.
- To test fuel pump resistance, use ohmmeter to check resistance between specified terminals on electrical connector for fuel pump. See Fig 1. Replace fuel pump if resistance is not .20-3.00 ohms at 68°F (20°C).CAUTION: When testing fuel pump operation, DO NOT apply battery voltage to fuel pump for more than 10 seconds, or fuel pump may be damaged. When testing fuel pump operation, keep fuel pump away from battery as far as possible.
- To test fuel pump operation, apply battery voltage and ground to (+) and (-) terminals on electrical connector for fuel pump. See Fig 1. DO NOT apply battery voltage to fuel pump for more than 10 seconds. Keep fuel pump away from battery as far as possible. Replace fuel pump if fuel pump does not operate.
