1. Listen for the pump:
* Turn the key to the "ON" position (not starting the engine). You should hear a whirring sound for a few seconds from the fuel tank area. This is the fuel pump priming the system. If you don't hear anything, the pump might be faulty, the relay is bad, or there's a wiring problem. This is the easiest initial check.
2. Check fuel pressure:
* This requires a fuel pressure gauge, which you can usually rent from an auto parts store. Consult your repair manual for the correct fuel pressure specification for your Aspire's engine.
* Connect the gauge to the fuel pressure test port (location varies depending on engine type; check your manual).
* Turn the key to the "ON" position. The gauge should show the specified pressure. If the pressure is low or nonexistent, the fuel pump is likely the culprit (though other components like the fuel filter or regulator could also be at fault).
* With the engine running, the pressure should remain stable and within the specified range.
3. Visual inspection (difficult and potentially dangerous):
* Access to the fuel pump is generally challenging and requires dropping the fuel tank. This should only be attempted by someone experienced with automotive repairs, as working with fuel systems carries a risk of fire or explosion.
* If you've already dropped the tank, you can visually inspect the pump for any obvious damage. You can also test it with a multimeter if you know how to test the motor's windings.
4. Check the fuel pump relay:
* The fuel pump relay is an electrical component that controls the pump. A faulty relay can prevent the pump from working even if the pump itself is good.
* Locate the relay in the fuse box (usually under the hood or in the passenger compartment) and swap it with a relay of the same amperage rating from another circuit (if possible and safe). If the pump now works, the old relay is bad.
5. Check the fuel pump fuse:
* Similar to the relay, a blown fuse can prevent the pump from operating. Consult your owner's manual to locate the fuel pump fuse and check if it is blown.
Important Considerations:
* Safety First: Working with fuel systems is dangerous. Always disconnect the battery's negative terminal before working on any fuel system components. Avoid sparks and open flames. Work in a well-ventilated area.
* Repair Manual: A repair manual specific to your 1995 Ford Aspire is invaluable. It will provide detailed information on the location of components, fuel pressure specifications, and troubleshooting steps.
If you're not comfortable performing these checks yourself, it's best to take your Aspire to a qualified mechanic for diagnosis and repair. Replacing the fuel pump is a relatively involved job, often requiring the tank to be dropped.
