Since you've already checked the location specified in your Haynes manual, your next step is to consult a wiring diagram specific to your *exact* 1997 Ford Aspire. This is crucial. A wiring diagram will show the relay's location and the circuit it's part of.
Here's how to proceed:
1. Find your VIN (Vehicle Identification Number). This number is unique to your car and will allow you to get precise information.
2. Use an online parts lookup: Several websites allow you to enter your VIN and obtain a parts diagram, often including relay locations. Some of these are subscription-based, but others may offer free limited access. Try searching for "Ford parts diagram VIN lookup."
3. Check the fuse box diagrams: Your owner's manual might have a detailed diagram of the fuse box (or boxes) showing the relay assignments. Even if it doesn't show the *exact* location, knowing which relay it is can help you locate it by comparing its physical appearance to the diagram.
4. Use a multimeter: If you're comfortable with basic electrical testing, a multimeter can help. You could trace the fuel pump wire back to its source (relay), or, with the key on, check for power and ground at the relay's terminals. *Always disconnect the battery's negative terminal before working with electrical components.*
5. Consult a Ford-specific forum: Online forums dedicated to Ford vehicles (particularly those focused on the Aspire) are valuable resources. Members there may have encountered similar issues and can provide location information based on their own experiences.
Possible Locations (but verify with your specific vehicle's information):
While the Haynes manual is inaccurate in your case, common locations for fuel pump relays in Fords include:
* Under the hood, in the main fuse box: This is the most common location.
* Inside the passenger compartment, under the dashboard: Less common, but possible.
* A separate relay center: Some vehicles have an additional relay center (often near the battery or under the hood).
Remember: Safety first. Always disconnect the battery's negative terminal before working with electrical components, especially relays. If you're uncomfortable working with automotive electrical systems, it's best to consult a qualified mechanic.
