Priority Order

1. Check dashboard lights — if none, battery is completely dead.

2. Wiggle the shifter to Park (automatic) or ensure clutch is fully pressed (manual).

3. Check the main fuse and starter relay.

4. If all electrical works but starter doesn't engage, check ignition switch and neutral safety switch.
