Instead of searching for a specific "engine fuse," you should:
1. Check the Starter Relay: This is a much more likely culprit than a blown fuse in this situation. The relay acts as a switch, sending high current to the starter motor. Its location varies slightly by year and trim, but it's usually in the underhood fuse box or a separate relay center (often near the battery). Consult your owner's manual for the precise location. You might be able to hear it click when you turn the key; if not, that's a strong indication the relay is at fault. Try tapping it gently (sometimes they stick). Replacing the relay is a cheap and easy fix.
2. Check the Battery and Cables: Ensure the battery has sufficient charge (use a voltmeter). Look at the battery cables (positive and negative) for corrosion or loose connections. Clean and tighten them if necessary. A bad connection can prevent the starter from receiving enough current.
3. Check the Ignition Switch: A faulty ignition switch can prevent power from reaching the starter circuit. This is harder to diagnose and usually requires professional help.
4. Check the Underhood Fuse Box: While there isn't a single "engine fuse," the underhood fuse box contains fuses that protect various circuits related to the engine's electrical system. Carefully examine all fuses in the box, looking for any that are blown (usually indicated by a broken filament). The fuse box diagram should be on the inside of the cover. If you find a blown fuse, replace it with one of the same rating. Don't just put in a higher amperage fuse – this could cause a fire.
5. Neutral Safety Switch: This switch prevents the starter from engaging unless the car is in park or neutral. A faulty switch could be the problem.
Before doing any electrical work, disconnect the negative battery cable to prevent accidental shorts.
If after checking these items, you still can't start the car, it's best to take it to a qualified mechanic. Trying to troubleshoot further electrical issues without proper knowledge could damage other components. The problem could be anything from a wiring fault to a problem with the ignition system itself.
