Why is there no power to my ignition coil?

You may have a bad ignition module. You can check it by removing the affected ignition coil, also remove the fuel injector fuse. Connect a test lamp across the two terminals on the ignition module. Take a look at the test light while you crank the engine over.

Does an ignition coil need power?

A gasoline-powered vehicle’s ignition coil gets power initially from the starter battery and, once the engine is up to speed, from the generator (usually an alternator with rectified DC output). Of course, the alternator charges the battery so you could argue that the ignition coil always gets power from the battery.

Where does coil pack get power from?

This allows the car’s computer to control a transistor that replaces the breaker points and opens or closes current as needed. A coil pack is a collection of ignition coils that transforms power from the automobile’s battery to generate spark to individually fire each cylinder.

How many volts should a coil put out?

Electricity Goes Out The average vehicle ignition coil puts out 20,000 to 30,000 volts, and coils used in racing applications are capable of 50,000 or more volts at a constant rate. This new voltage is then routed to the distributor via the coil wire, which is just like the spark plug wires, only normally much shorter.

Can a bad distributor cause no spark?

A faulty engine distributor won’t spark, which will either prevent the engine from starting or cause it a running engine to fail. In order for the ignition system to work properly it is important to keep the engine distributor operating at maximum efficiency.

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.
