Kohler Generator Won't Start? Causes, Checks and Common Problems

A Kohler generator that cranks but won't start, or won't crank at all, usually comes down to fuel, air, compression or electrical. Here is what our mobile mechanics check first, plus the other problems we see most on Kohler generator equipment.

South Florida

Why a Kohler Generator Won't Start

Dead or weak batteries and corroded cables, a failed starter or relay, air in the fuel system, clogged fuel filters, a bad lift pump, seat and neutral safety switches, glow plug or intake heater faults, and low compression on high-hour engines. Other searches we hear about Kohler generator: won't start, will not start, starts then dies.

What You Can Check Before Calling

Battery voltage, fuel level and filters, the safety switches, and any codes on the monitor. If the engine cranks strongly but won't fire, stop cranking and call — repeated cranking damages the starter and can hydro-lock a cylinder.
