Fuel Pump Inspection
- Fuel pump is located inside fuel tank. Locate DLC-1 on left side of engine compartment. Connect a fused jumper wire between DLC-1 terminals F/P and GND. On 626, remove fuel pump relay and ground relay socket terminal No. 30. See Figure or Figure . Remove fuel filler cap. Turn ignition switch on. Listen for fuel pump operation at fuel filler pipe. Install fuel filler cap.
- If fuel pump does not operate, Disconnect fuel pump connector. Using DVOM, check for continuity between fuel pump connector terminals "B" and "D" (terminals "A" and "D" on 626). If continuity is not present, replace fuel pump. If continuity is present, check for open or short circuit in wiring harness between fuel pump and fuel pump relay. See WIRING DIAGRAMS article.
