Before You Begin:
* Safety First: Fuel is highly flammable. Work in a well-ventilated area, away from any open flames or sparks. Wear safety glasses. Have a fire extinguisher handy.
* Consult your workshop manual: A factory service manual for your specific year and model Falcon will provide the most accurate and detailed instructions. This is highly recommended.
* Identify the fuel system components: Locate the fuel tank, fuel pump, fuel filter, fuel lines, and fuel injectors (or carburetor, depending on the year).
General Bleeding Procedure (After Fuel Pump Replacement or Repair):
1. Check for Leaks: Before attempting to bleed the system, thoroughly inspect all fuel lines and connections for leaks. Tighten any loose connections.
2. Prime the Fuel Pump (if applicable): Some fuel pumps require priming. Your workshop manual will detail this. It often involves turning the ignition key to the "ON" position (but not starting the engine) for a few seconds several times. This helps build initial pressure in the system.
3. Check Fuel Filter: Ensure the fuel filter is properly installed and not clogged.
4. Listen for the Fuel Pump: With the key in the "ON" position, listen for the fuel pump to run. You should hear a whirring sound. If you don't, this indicates a problem that must be addressed *before* bleeding the lines.
5. Cranking the Engine (without starting): Turn the ignition key to the "START" position for several short intervals (a few seconds at a time), allowing the fuel pump to continue to pressurize the system. *Do not crank for extended periods without the engine catching.* This will help push air out of the lines.
6. Check for Fuel at the Injectors/Carburetor: Look for fuel spraying from the injectors (if fuel-injected) or flowing into the carburetor (if carbureted) during cranking.
7. Repeat Steps 4-6 as Needed: Continue this process until fuel is consistently delivered.
Bleeding After a Fuel Filter Change:
The procedure is similar to the one above, but often simpler. Priming might not be necessary, and you might only need a few crank attempts to push the air out of the new filter.
Bleeding After a Fuel Line Repair:
After repairing a fuel line, ensure all connections are tight and secure. Then, follow steps 1-7 above. You might need to pay particular attention to the repaired section to make sure there are no air pockets.
Important Notes:
* If the engine still won't start after repeated attempts, there's likely a more serious problem. This could involve a faulty fuel pump, clogged fuel filter, electrical issues, or another component failure.
* If you're uncomfortable working on your fuel system, take your vehicle to a qualified mechanic. Improperly working with fuel can be dangerous.
Remember to consult your specific workshop manual for your Ford Falcon model year. It will offer precise instructions and diagrams unique to your vehicle. This response provides a general overview, but the details can vary.
