Q: Spark plug not firing

asked by on

The spark plug is not firing.

HI there. If you’re not getting spark to any of the plugs, you’ll want to look at the ignition components that are "up stream". In your vehicle, the crankshaft position sensor sends a signal to the ignition module. The module then passes this information to the ECM, which in turn, controls ignition coil operation to fire the spark plugs. In your situation, I would focus on components common to all of the cylinders; namely the crankshaft sensor and ignition module. I suggest you have a trained professional diagnose the no-start condition your vehicle is encountering and replace any failing components.
