my Ford F-150 13th Generation (2015-2020) loses power after hitting bumps

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the engine is turned off and cool.
• Disconnect the battery to prevent any electrical shorts.

2. Inspect and Secure Battery Connections

• Sub-steps:
  1. Remove the battery terminals, starting with the negative (-) terminal.
  2. Clean any corrosion from the terminals and battery posts using a wire brush.
  3. Reattach the terminals securely, ensuring a tight fit.

3. Inspect Fuel System

• Sub-steps:
  1. Locate the fuel pressure test port on the fuel rail.
  2. Use a fuel pressure gauge to check the fuel pressure against manufacturer specifications.
  3. If pressure is low, check the fuel pump, filter, and lines for clogs or damage.
  4. Replace the fuel filter if necessary.

4. Inspect Engine and Transmission Mounts

• Sub-steps:
  1. Visually inspect the engine and transmission mounts for cracks or wear.
  2. If damaged, use a socket set to remove the bolts securing the mounts.
  3. Replace with new mounts and torque to manufacturer specifications (typically around 40-60 ft-lbs).

5. Inspect Wiring Harnesses

• Sub-steps:
  1. Trace the wiring harnesses from the battery to the engine and fuel system.
  2. Look for frayed wires, loose connectors, or signs of damage.
  3. Repair or replace any damaged wiring or connectors as needed.

6. Test Ignition System

• Sub-steps:
  1. Remove the spark plugs using a socket wrench and inspect them for wear or carbon buildup.
  2. Replace spark plugs that show signs of damage or excessive wear.
  3. Check ignition coils for proper resistance using a multimeter.
  4. Replace any faulty ignition coils.
