Solution

1. Preparation

Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Clean Battery Connections

Remove both positive and negative battery terminals.
Clean terminals and battery posts with a wire brush and apply anti-corrosion grease.
Reconnect the terminals, ensuring they are tight.

3. Test and Replace the Starter Motor (if necessary)

Locate the starter motor (usually near the transmission).
Disconnect the electrical connector and the battery cable from the starter.
Use a multimeter to test the starter for continuity.
If defective, remove the starter motor (typically requires a socket set).
- Sub-steps:
  - Support the vehicle securely on jack stands.
  - Remove the bolts securing the starter to the engine.
  - Install the new starter motor, tightening bolts to manufacturer specifications (typically 15-20 ft-lbs).
  - Reconnect the battery cable and electrical connector.

4. Check Fuel Pump Relay and Wiring

Locate the fuel pump relay in the fuse box and test it for continuity.
Inspect wiring to the fuel pump for any damaged insulation or disconnections.
Replace any faulty components if necessary.
