how to fix my Toyota Tacoma N300 (2016-Present) if it stalls after starting

Solution

1. Preparation

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

2. Fuel System Inspection

• Sub-steps:

  1. Connect the fuel pressure gauge to the fuel rail.
  2. Turn the ignition to the "On" position (do not start) and check the pressure reading; it should be within the manufacturer's specified range (typically around 50-60 psi).
  3. If pressure is low, inspect the fuel pump, fuel filter, and fuel lines for blockages or leaks.
  4. Replace any faulty components as needed.

• Tools Required:

  • Fuel pressure gauge
  • Wrenches and pliers

3. Air Intake Inspection

• Sub-steps:

  1. Remove the air intake duct and inspect the air filter; replace if dirty.
  2. Check for any vacuum leaks in the hoses connected to the intake manifold.
  3. Clean the throttle body using throttle body cleaner and a soft cloth.

• Tools Required:

  • Screwdrivers
  • Throttle body cleaner

4. Ignition System Check

• Sub-steps:

  1. Remove the spark plug wires and inspect for wear or damage; replace if necessary.
  2. Remove the spark plugs and check their condition; replace if fouled or worn.
  3. Test the ignition coils for proper resistance using a multimeter.

• Tools Required:

  • Socket set
  • Multimeter
  • Torque wrench (for reinstallation)

5. Electrical System Check

• Sub-steps:

  1. Test the battery voltage; it should be around 12.6 volts with the engine off.
  2. Inspect battery terminals and cables for corrosion or loose connections; clean and tighten as necessary.
  3. Check the alternator output when the engine is running to ensure it is charging correctly (should be above 13.5 volts).

• Tools Required:

  • Multimeter
