Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Test the Ignition System

Tools Required: Spark plug socket, multimeter.
Remove the ignition coil(s) and spark plug(s) from the engine.
Use a multimeter to check for continuity in the ignition coil.
Inspect spark plugs for wear or damage; replace if necessary.
Reinstall the components after testing.

3. Check the Fuel System

Tools Required: Fuel pressure gauge.
Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge to the port and turn the ignition to the "ON" position (do not start).
Check the reading on the gauge; it should meet manufacturer specifications (typically around 40-50 psi for a Camry).
If pressure is low, check the fuel pump relay and wiring.

4. Inspect the Starter Motor

Tools Required: Socket set.
Locate the starter motor under the vehicle.
Check all electrical connections to the starter for tightness and corrosion.
Use a multimeter to check if the starter receives voltage when attempting to crank the engine.
If the starter is faulty, remove it and replace it with a new unit.
