What Fuse to Pull to Make a Car not Start?

Many car owners are in the lurch as a result of theft incidents. Some people have chosen to engage a security squad to prevent their cars from being stolen. However, this seems inevitable given the sophisticated methods auto thieves employ to escape with a vehicle.

The best action is to turn off the car by removing a fuse from the ignition system. It stops the starter solenoid from receiving power. Here are some of the fastest and most reliable techniques to disable a vehicle:

Starter Circuit

A blown fuse could cause a no-start issue in the starter circuit. Broken or corroded wiring can prevent the starter from receiving enough power. Damaged or filthy wires to the battery or the starter solenoid (or unsecured wires) might cause this. The battery is also recharged by it.

Ignition Switch Fuse

When starting the car, the gadget in the steering column is essential. The vehicle cannot run while the fuse is removed from the box. It is the quickest and most straightforward approach to take into account.

Gasoline Pump Fuse

The fuel system is typically turned off when the fuel pump fuse is removed. It interrupts the power supply to the spark plugs, injectors, and fuel pump. The method ultimately renders the car entirely immobile.

Take the Spark Plug Cables Off

The power for accelerating combustion and starting the engine is cut when the spark plug wires are removed. Therefore, these cables, which are typically found beneath the car hood, should be handled carefully to prevent further damage.

What is the Simple Way to Disable a Car?

# Cut the Battery Cable Connections

The most traditional way to prevent an automobile from starting is probably to disconnect the battery wires, but this approach is practical.

Varied vehicles have different locations for car batteries. However, the majority of batteries are either in the car trunk or the battery box under the hood.

The negative battery cable must be unbolted and disconnected by lifting it free in order for a car to start. Disconnecting the battery will deactivate any fuel-powered vehicle, whether diesel or gasoline-powered.

# Completely Clog The Air Filter

In the combustion chamber of an automobile engine, fuel and air are combined to produce power. The engine needs enough air to pass through the air filter to function properly.

Because of this, a car won’t start if the air filter is blocked or is not in the proper location. An automobile will become immobile if its air filter becomes clogged.

Strangely, even though you placed anything under the air filter, it appears to be in good condition from the outside. The car owner won’t be able to tell if the air filter is clogged without making adequate checks. But whenever you clog the air filter, you must keep in mind that the engine of the car requires a sizable amount of air supply to function; therefore, blocking or clogging the air filter can harm the engine.

# Deflate Each of The Four Tires

The difficult but effective approach to stop a car from starting for a while is to let the air out of all of your car tires.

How to properly deflate tires:

  1. First, find the tire’s valve stem.
  2. Remove the valve stem cap from the stem, turn it counterclockwise with your finger.
  3. The metal pin should be pushed inward by placing the flat-head screwdriver’s tip over the top of the pin.
  4. Check the tire pressure after releasing the screwdriver from the valve stem.
  5. After that, air will escape from the tires through the valve stem.

# Spray The Air Intake With Water

The potential outcome of completely soaking the air filter is that the car may not drive correctly. In these circumstances, soaking the air filter requires a significant volume of water.

However, soaking the air filter could have had some unfavorable consequences, such as damage to the engine and the air intake system, as well as the possibility of blocked vacuum valves in the car. Consequently, you must take care anytime you clean the car’s engine.

Are Fuse Removals Safe?

Yes. The car won’t suffer any harm. Removing it and leaving it out is the best course of action. However, it will prevent the car from starting or moving.


One method to turn it off is removing the vehicle’s fuse. The strategy is helpful for automobile owners who reside in neighborhoods where theft is common. You can avoid paying expensive insurance company rates by using this strategy.

The other techniques described in the article have also successfully and efficiently immobilized the car. Select the suggestion based on your needs and the area. Be aware that some tactics may harm your vehicle.
