After an accident in a 1996 Saturn, several things could prevent the fuel pump from working, and it might seem like the fuel relay is the problem:
* Damaged Wiring: The accident could have damaged the wiring leading to the fuel pump, the fuel relay, or even the fuel pump itself. This is the MOST likely culprit after an accident. Check all wiring visually for breaks, shorts, or damage near the fuel pump and relay.
* Blown Fuse: Check the fuse box for a blown fuse related to the fuel pump or injection system. Consult your owner's manual to identify the correct fuse.
* Faulty Fuel Pump: The accident could have damaged the fuel pump itself. This often requires dropping the fuel tank to access and replace.
* Faulty Fuel Relay: While possible, this is less likely than the above issues after a collision. You might test the relay for continuity with a multimeter (if you have one and know how to use it safely), but replacement is simpler and more likely to solve the problem if it's genuinely faulty. The relay itself is relatively inexpensive.
What to do:
1. Safety First: Disconnect the battery's negative terminal before attempting any electrical checks or repairs. This prevents accidental shorts and sparks.
2. Inspect Wiring: Carefully examine all wiring related to the fuel system, paying close attention to areas that may have been impacted by the accident.
3. Check the Fuse: Locate and inspect the fuel pump fuse.
4. Test the Fuel Relay (if comfortable): If you're comfortable working with electricity and have a multimeter, you can test the relay's continuity. Otherwise, skip this step and proceed to replacement.
5. Replace Parts: If any wiring is damaged, repair or replace it. Replace any blown fuses. If the fuel pump or fuel relay is suspected to be faulty, replace them. These are best left to a qualified mechanic unless you have significant automotive experience.
In short: Don't try to "restart" the relay. Focus on checking the fuses, wiring, and the fuel pump itself, then replace any faulty components. Because you're dealing with post-accident damage, it's strongly recommended to have a qualified mechanic diagnose and repair the fuel system. Improper repairs could lead to further damage or even fire.
