If you're having fuel delivery problems, the issue isn't likely a switch. Instead, you should look at:
* Fuel pump relay: This is a more likely culprit. It's an electrical component that acts as a switch for the fuel pump. Its location varies slightly depending on the specific model and engine, but is typically found in a fuse box (under the hood or inside the car). Consult your owner's manual or a repair manual for its exact location.
* Fuel pump itself: The pump could be failing.
* Inertial switch: This safety device cuts power to the fuel pump in a collision. It's usually located under the dash or in the engine compartment and might need to be reset if tripped.
* Computer (PCM): Problems with the Powertrain Control Module can affect fuel pump operation. This requires diagnostic tools to check.
* Wiring: Damaged or corroded wiring leading to the fuel pump is another possibility.
Before attempting any repairs, consult a repair manual specific to your 1992 Dodge Shadow's engine (2.2L or 2.5L). This will provide diagrams and troubleshooting information. Improperly working on the fuel system can be dangerous due to the flammability of gasoline.
