What causes no spark to the spark plug?

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.

Why do I have power to my coil but no spark?

There are a few reasons for no spark, new coil pack could be defective, crank sensor, ignition module or bad wire in primary circuit, faulty ECM/PCM. You may have to have a good technician have a look, diagnose and estimate repair. Second link gives detailed instructions for testing and diagnosing coil pack.

Why is my bike not getting spark?

If the spark is weak or orange, it is probably your coil not generating enough voltage. Test for spark by touching the spark plug to the engine and pushing the starter. While you're at it, make sure the spark plug hole is not full of water. That is sure to cause spark problems.

Why is my ignition coil not firing?

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 would cause a spark plug not to fire?

A spark plug won't fire properly if its electrodes have been worn thin, if they are covered with combustion deposits or if they're wet. If the plug has seen many hours of service, the electrodes may just be worn out, and replacing the plug will restore normal engine operation.

Can ECM cause no spark?

It is extremely rare for a no spark condition to be the result of a faulty coil or ECM. Users get fixated on these items and jump to the conclusion they must be responsible for their problem because these items are easy to see and replace.

Can a bad ground cause no spark?

Bad grounds can cause no spark issues though. It can cause the ground to ground through the ecu frying it. If you get a single spark when turning on the ignition then nothing when cranking it's the ecu. It's a really good idea to go over all your grounds on a regular basis anyway.

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. ... That moves other distributor parts that cause the ignition coil to pulse, and sends the electricity down each spark plug wire in order.

What controls spark on a motorcycle?

Essentially, a CDI box controls a motorcycle's ignition system by starting the ignition and combustion process. A pulse of voltage from the motorcycle battery passes through the CDI box to fire up the spark plug.

Can ignition switch cause no spark?

No spark is one of the most common causes of a no-start condition. It's the first thing I check for. ... The igniter or ignition module, the pick up coil or crank sensor, the cam sensor, and the ignition switch are included.
