Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
If you have a good spark on all wires look for timing problems or other issues. If you do not have a good spark in all wires then you may have an electrical problem in your ignition system.
The coil and plug won’t produce a spark so long as the control wire is connected to ground (Metal of engine). A common fault is chafing of the control wire on the engine (shorting to ground), this effectively is the same as releasing the bail lever – turns engine off.
There might be different reasons when the spark plug is not firing and you have to troubleshoot to know the actual culprit behind this no spark condition. If the spark plug is not initiating a normal spark the engine will not start the fire and thus you won’t be able to run the Kholer engine like any other engine.
How do I fix no spark?
If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot).

How do you diagnose a car with no spark?
If the ignition coil does not have spark, it’s time to check its wires. Use a test light to check the continuity on the signal wire and power wire on the ignition coil. If both wires are functional but the coil fails to produce spark, the ignition coil or the ignition control module is bad.
What sensor would cause no spark?
A Bad Crankshaft Position Sensor The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn’t know when to fire the fuel injectors and ignite the spark plugs.

What stops a coil from firing?
A bad coil or a cracked distributor cap can stop the spark plugs from firing.
What sends spark to the coil?
The ignition system is divided into two sections, the primary circuit and the secondary circuit. The low voltage primary circuit operates at battery voltage (12 to 14.5 volts) and is responsible for generating the signal to fire the spark plug at the exact right time and sending that signal to the ignition coil.
How do I troubleshoot no spark?
If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot). Place the spark plug on a metal surface on the engine, or ground the spark plug tester to the engine. Then crank the engine to check for a spark.
Should a 12 volt coil have power on both sides?
Yes, if the points are open and/or the electronic module is NOT CLOSED then you will measure battery voltage on both the coil (+) and coil(-) terminals. Since there is no current flowing through the coil (no path to earth) then both sides of the coil will be at the same potential.
What would cause no spark to spark plugs?
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
How do you test a 12 volt ignition coil?
To check your coil, ensure you have 12V going to the positive terminal. Once you confirm that is the case pull the wire out of the centre of the distributor and hold it a cm away from the distributor centre terminal. Have someone crank over the engine, and there should be a nice blue spark..
What gives power to the ignition coil?
The battery provides low voltage electricity to the ignition coil. The ignition coil converts the low voltage electricity into high voltage power in timed pulses. The distributor has a shaft that gets spun by the camshaft.
