1. Listen for the Pump (Easiest, but least conclusive):
* Turn the ignition key to the "ON" position (don't start the engine). You should hear a brief humming sound from the fuel tank area (usually in the rear of the vehicle). This sound lasts only a couple of seconds and indicates the pump is priming the fuel system. If you don't hear anything, the pump *might* be faulty, but other issues could also cause this.
2. Check Fuel Pressure (Most Reliable):
This requires a fuel pressure gauge, which you can usually rent or borrow from an auto parts store. Caution: Fuel is flammable, so be extremely careful when working with it.
* Locate the fuel pressure test port. This is usually on the fuel rail, a metal bar running along the top of the engine near the intake manifold. Consult your owner's manual or a repair manual specific to your 2000 Ford Contour for its exact location.
* Connect the fuel pressure gauge to the test port.
* Turn the ignition to the "ON" position (don't start the engine). The gauge should show the specified pressure for your Contour's engine (check your owner's manual or a repair manual). This pressure is usually between 30 and 40 PSI but can vary.
* If the pressure is low or doesn't build up, the fuel pump could be weak or failing. Other possibilities include a clogged fuel filter, faulty pressure regulator, or leaks in the fuel lines.
3. Inspect the Fuel Pump Relay (Intermediate):
A faulty fuel pump relay can prevent the pump from working.
* Locate the fuel pump relay in the underhood fuse box. Your owner's manual or a repair manual will show you the relay's location and its identification.
* Visually inspect the relay for any damage. Look for burnt contacts, corrosion, or loose connections.
* Swap the relay with a known good relay of the same amperage (from a different circuit). If the problem goes away, the original relay is faulty.
4. Test the Fuel Pump Directly (Advanced - Requires Electrical Knowledge):
This involves accessing the fuel pump, usually by dropping the fuel tank. This is considerably more complex and requires specific knowledge and safety precautions.
* Disconnect the fuel pump wiring connector.
* Use a multimeter to check for power at the connector. With the ignition on, you should have power at the appropriate wires. If not, there could be a problem with the wiring, fuse, or relay.
* You might also be able to use a test light to check the power supply.
* With the fuel pump disconnected, apply 12V directly to the pump's terminals. If it runs, the problem likely lies elsewhere in the circuit. Be very careful when doing this because it can be hazardous.
Important Considerations:
* Safety First: Always disconnect the negative battery terminal before working on any fuel system component. Fuel is flammable and explosive. Work in a well-ventilated area.
* Repair Manual: A repair manual for your specific 2000 Ford Contour will be invaluable. It will provide detailed diagrams and instructions.
* Professional Help: If you are uncomfortable performing any of these checks, it's best to take your vehicle to a qualified mechanic. Incorrectly handling the fuel system can be dangerous.
The fuel pressure test (step 2) is the most reliable way to diagnose a fuel pump problem. The other steps help narrow down the possibilities, but the pressure test will tell you definitively if the pump is delivering the required fuel pressure.
