Fuel Pump Resistance & Operation
- Remove rear seat and cover plate on floor panel for access to electrical connector at fuel pump.
- To test fuel pump resistance, using ohmmeter, check resistance between specified terminals on fuel pump electrical connector. See Fig 1. Replace fuel pump if resistance is not .20-3.0 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 to operate.
