Common Reasons Your Toyota Yaris May Not Start

Dead Battery

Faulty Starter Motor

    • Solution:The starter motor may need to be repaired or replaced if it’s not functioning properly.

Alternator Issues

    • Symptoms: The car starts but then stalls, or the battery warning light is on.
    • Solution:If the alternator isn’t charging the battery properly, the battery will drain even while driving. The alternator may need to be repaired or replaced.

Ignition Switch Problems

    • Symptoms:No response when turning the key, or the key won’t turn in the ignition.
    • Solution:The ignition switch could be faulty or worn out. This may require repair or replacement.

Fuel System Issues

    • Symptoms:The engine cranks but doesn’t start, or it starts and then dies shortly after.
    • Solution: Check if there’s fuel in the tank. If there is, the fuel pump, fuel filter, or fuel injectors might be the issue. These components may need cleaning, repair, or replacement.

Faulty Spark Plugs

    • Symptoms:The engine cranks but struggles to start, or it runs rough after starting.
    • Solution:Spark plugs may be worn out or fouled, which can prevent the engine from starting. Replacing the spark plugs is often the solution.

Clogged Air Filter

Security System Malfunction

    • Symptoms:The engine doesn’t start, and a security warning light may be on.

Transmission in the Wrong Position
