Fuel Pump Resistance & Operation

Disconnect electrical connector for fuel pump. See «FUEL PUMP ELECTRICAL CONNECTOR LOCATION»(ref-95581-S15205925472001040200000) table. FUEL PUMP ELECTRICAL CONNECTOR LOCATION Application Connector Location Camry, Celica & Corolla Under Cover Plate, Below Rear Seat RAV4 Under Cover Plate, Below Driver's Side Rear Seat Tacoma On Top Of Fuel Tank At Fuel Pump Tercel Under Cover Plate, Below Rear Seat T100 On Top Of Fuel Tank, Near Fuel Pump 4Runner On Top Of Fuel Tank At Fuel Pump
To test fuel pump resistance, use ohmmeter to check resistance between specified terminals on fuel pump electrical connector or fuel pump. (Scheme 55)- (Scheme 62). 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. (Scheme 55)- (Scheme 62). 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.
