The following information will help you detect engine troubles and take corrective action.
Engine does not fire
If the engine fails to fire, the trouble can usually be traced to the battery, spark plug, or engine.
Ignition battery voltage low trouble generally occurs before the engine gets too low to perform the required work. The failure is normally preceded by charging or replacing battery.
Battery wires faulty or loose can deteriorate with age causing misfires, hard starting and poor performance. Wires should be replaced or reconnect.
Spark plugs, well, spark the combustion in your engine; it plays a vital role in keeping the engine running. If the spark plugs are all gunked-up or misfiring, the engine won't be running and starting properly. This can be done by removing the spark plug from the cylinder of the engine, inserting the plug onto the plug cap, and contacting the plug to the outside of the crankcase. Have an assistant turn the engine over while checking this and be sure to have the spark plug firmly plugged into the ignition wire.
Warning: The high voltage from the ignition can cause bodily harm, especially when checking for spark in this manner.
