Troubleshooting

In engines equipped with a Start Sense system, if the engine will not start, check oil level and bring level to FULL. If engine still does not start, disconnect lead at the oil fill plug/terminal. If engine starts, the module is faulty, or the internal crankcase float is sticking. Clean or replace parts as necessary.

In engines equipped with a Run Sense system, if the engine halts during operation, or will not remain running upon starting, check oil level. if oil level is at FULL and engine continues to halt, the module is faulty or the internal crankcase float is sticking. Clean or replace parts as necessary.
