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.
