To find it, you'll need to consult your vehicle's owner's manual or a repair manual specific to that year and model. These manuals will typically have a diagram showing the relay locations in the fuse box(es). There might be multiple fuse boxes; one under the hood and possibly one inside the car.
Alternatively, you can try these steps:
1. Check the under-hood fuse box: This is the most likely location. The fuse box cover usually has a diagram showing the location of relays and fuses. Look for a relay that's labeled "Fuel Pump" or something similar, or check a wiring diagram (available online or in a repair manual) to see which relay controls the fuel pump.
2. Check the interior fuse box (if present): Some models have additional fuse boxes inside the car, often near the steering column or under the dash.
3. Use a wiring diagram: A wiring diagram for your specific year and model of the Plymouth Laser RS is crucial. This will show you exactly which relay is connected to the fuel pump circuit. You can usually find these online through sites specializing in automotive repair information (some are subscription-based).
Important Note: Before working with any electrical components, always disconnect the negative terminal of your battery to prevent accidental short circuits.
