How Can I Check To See If An Ignition Coil Is Any Good On A 1995 Chevy Blazerit Does Not Spark While The Wire Is Removed And Held Close To It?
The coil will not spark, the coil provides constant steady power to the rotor. In turn, the rotor distributes the power to each individual spark tower in the cap, like a garden sprinkler distributing water, which then travels through each wire to each spark plug. Check for spark at the plugs first. If there’s no spark there, the issue could be within the coil, the distributor, or the ignition module. Coils and modules can be tested at most parts stores to detirmine if they are the cause. By the way, be very careful, I would not want to be on the receiving end of the 50,000 volt shock your coil is capable of producing.
