  If your TOHATSU Outboard Motor engine won't start, several factors could be at play. First, make sure the fuel tank isn't empty and refill it if necessary. Then, verify the fuel system connections are correctly set up. Inspect the fuel line for any potential leaks that might be letting air in. A deformed or damaged fuel hose should be replaced. Ensure the air vent on the fuel tank is open, and check for any clogs in the fuel filter, fuel pump, or carburetor, cleaning or replacing them as needed.
