A: As you may know, ignition coils are made up...

As you may know, ignition coils are made up of a series of would up copper coils which generate and hold current to be released to the spark plug wires. These coils are insulated with a thin material that sometimes can become brittle and crack over time due to excessive heat generated in the engine bay. When this happens, the coil wire then becomes exposed sometimes creating a short which can cause it to not function properly or at all. When this happens, you may experience a loss of spark. I would recommend having an expert from YourMechanic come to your location to take a look at your truck to properly diagnose your ignition system.
