If The F-150 Doesn't Crank

• 1). Attempt to ump start the battery on the F-150. Be sure to use heavy duty jumper cables and attempt the jump using a battery with comparable voltage.
  
  
• 2). If the jump start is successful, allow the engine to idle for 10-15 minutes in an attempt to charge the battery.
  
  
• 3). Shut off the engine, remove the jumper cables, and attempt to restart the F-150. Replace the battery if the truck still fails to start at this point.
  
  
• 4). Consult a qualified mechanic to inspect the ignition switch, starter, and other components of the ignition system if jump starting the F-150 is not successful.
  
  

If The F-150 Cranks, But Will Not Start

• 1). Check the truck's fuel level. The fuel tank could be empty, meaning the problem is a bad fuel gauge.
  
  
• 2). Procure a spark tester and test all spark plugs. All faulty plugs will need to be replaced as the air/fuel mixture will be unable to ignite and start the engine.
  
  
• 3). Remove the timing belt cover. If the timing belt is either snapper or out of position, it will need to be replaced or repositioned by a qualified mechanic, as the process involves removing many engine components.
  
  
• 4). Turn the key in the F-150 until the electronics are powered up. Listen carefully to determine if the fuel pump is pressurizing the fuel injection system. If no noise can be heard, the fuel pump may be faulty.
