Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Inspect and Replace Battery

Tools Required: Wrench set, multimeter
Use a multimeter to check the battery voltage; it should be above 12.4 volts.
If the battery is weak or old, replace it with a new, compatible battery for the F-150.
Reconnect the negative battery terminal.

3. Fuel System Inspection

Tools Required: Fuel pressure gauge, safety goggles
Attach the fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position without cranking the engine.
Check the fuel pressure; it should be within manufacturer specifications (typically around 30-45 psi).
If the pressure is low, check the fuel pump and fuel filter. Replace the fuel filter if clogged and test/replacement of the fuel pump if necessary.

4. Spark Plug and Ignition Coil Check

Tools Required: Socket set, torque wrench
Remove the spark plugs using a socket set and inspect for wear or carbon buildup.
Replace worn spark plugs with OEM recommended parts.
Test ignition coils using a multimeter; replace any faulty coils.

5. Fuel Injector Cleaning or Replacement

Tools Required: Injector cleaning kit or replacement injectors
If injectors are clogged, clean them using an injector cleaning kit.
If cleaning does not resolve the issue, replace the injectors with new OEM parts.
