Why Toro TITAN MX5480 Lawn Mower engine will not start?
- BBenjamin JonesAug 15, 2025
There are several reasons why your Toro Lawn Mower engine might not start. It could be due to an empty fuel tank, a closed fuel shutoff valve, or a low oil level in the crankcase. The throttle and choke may not be in the correct position. Other potential causes include a dirty fuel filter, dirt, water, or stale fuel in the fuel system, a dirty air cleaner, or a faulty spark plug. Also, check the spark plug wire connection and the seat switch indicator. Clean connector terminals thoroughly with electrical contact cleaner, apply dielectric grease and reconnect if electrical connections are corroded, loose or faulty.
