Look for fuses related to:
* Ignition Switch: This controls power to the ignition system.
* Ignition Coil: This provides the high voltage spark.
* Fuel Pump (if applicable): Some fuel pumps are ignition-switched.
Without the owner's manual, providing precise locations is impossible and risky. Incorrectly replacing fuses can cause further damage. The owner's manual is your best resource for this information. You can often find a downloadable PDF version online if you don't have the physical manual.
