To find it, you'll need to:
1. Consult your owner's manual: This is the best place to start. It will have a diagram showing the location of all relays and fuses.
2. Look in the under-hood PDC: This is the most likely location. The PDC is usually a large black box, often near the battery. The cover will have a diagram showing the location of relays and fuses. Look for a relay labeled "fuel pump," "fuel system," or something similar. The diagram will likely use symbols or numbers to identify it.
3. Check the interior fuse box (less likely): If you can't find it under the hood, check the fuse box inside the passenger compartment. Again, consult your owner's manual for the diagram.
Important Note: Before working with any electrical components, disconnect the negative terminal of your battery to prevent accidental short circuits.
If you can't find it after checking both fuse boxes and using your owner's manual, a search online for "2000 Dodge Stratus fuel pump relay location [engine size]" (replace "[engine size]" with your engine's displacement, e.g., "2.4L") might yield more specific information from online forums or repair manuals.
