my Toyota RAV4 Fifth Generation (2019-present) won't start after filling gas what to do

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuel Pump Relay

• Locate the fuel pump relay in the fuse box (refer to the owner's manual for exact location).
• Remove the relay and test it with a multimeter for continuity.
  • Tools Required: Multimeter
• If the relay is faulty, replace it with a new one.

3. Check Fuel Pump Operation

• Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
• Listen for the fuel pump activation sound (a humming noise) from the rear of the vehicle.
• If there is no sound, the fuel pump may need to be replaced.
• If the pump is operational but the engine still won't start, proceed to inspect the fuel filter for clogs.

4. Inspect and Replace Fuel Filter

• Locate the fuel filter (may vary by model).
• Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
• Disconnect fuel lines from the filter, taking care to catch any spilled fuel.
• Remove the old filter and install the new one, ensuring proper orientation.
  • Tools Required: Wrench set, fuel line disconnect tool
• Reconnect fuel lines and fuse.

5. Verify Ignition System

• Inspect ignition components like spark plugs and ignition coils.
• Replace any faulty components as necessary.
• Tools Required: Socket set, torque wrench
