•Allow the engine to cool before inspecting any components

Symptoms

•Engine cranks but does not start
•Dashboard lights illuminate but engine does not fire
•No clicking sound from the starter
•Fuel gauge indicates fuel is present
•No error codes present on the OBD-II scanner

Diagnostic Steps

1
Check the battery voltage with a multimeter to ensure adequate charge (12.4 volts or higher)
2
Inspect battery terminals for corrosion and ensure tight connections
3
Test the starter motor by applying direct power to the starter solenoid
4
Verify fuel pump operation by listening for a humming sound when the ignition is turned on
5
Check for spark at the ignition system by removing a spark plug and using a spark tester
6
Inspect fuses related to the fuel system and ignition system for continuity

Solution

Solution

1. Preparation

Gather tools: multimeter, socket set, spark tester, and screwdrivers.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection

Sub-step 1: Disconnect the battery by removing the negative terminal first, followed by the positive terminal.
Sub-step 2: Clean any corrosion from the terminals using a wire brush.
Sub-step 3: Reconnect the battery, starting with the positive terminal followed by the negative terminal.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor under the vehicle.
Sub-step 2: Use a jumper wire to connect the positive terminal of the battery directly to the starter solenoid terminal.
Sub-step 3: Observe if the starter engages. If it does not, the starter may need replacement.

4. Fuel System Check

Sub-step 1: Locate the fuel pump relay and remove it from the fuse box.
Sub-step 2: Use the multimeter to test for voltage at the fuel pump connector while the ignition is in the ON position.
Sub-step 3: If voltage is present but the pump is not functioning, replace the fuel pump.

5. Ignition System Check

Sub-step 1: Remove a spark plug wire and insert a spark tester into the wire.
Sub-step 2: Crank the engine and observe the tester for a spark.
Sub-step 3: If no spark is present, replace the ignition coil or related components.
