To test fuel pump resistance, use ohmmeter to check resistance between specified terminals on fuel pump electrical connector or fuel pump. See Fig 1-Fig 8 . 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 or fuel pump. See Fig 1-Fig 8 . 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 fails to operate.
