  If your TOHATSU Outboard Motor engine isn't starting, there could be several reasons: * The fuel tank might be empty, in which case, you should fill it. * There might be an incorrect connection of the fuel system, so check and correct the fuel system connections. * Air could be entering the fuel line; inspect and seal any leaks. * A deformed or damaged fuel hose may be the culprit, replace it if needed. * The air vent on the fuel tank might be closed; open it. * Finally, the fuel filter, fuel pump, or carburetor could be clogged; clean or replace these components.
