what are the symptons of a faulty engine module on a v6 02 chevy malibu and how to replace one?

Answer 1

Symptoms are a no start condition, an intermittent no start condition, or a bad misfire as it won't fire a coil. These aren't too bad to change out as all you have to do is disconnect the electrical connections, take all the spark plug wires off, and then remove all the coil bolts and the module with coils will fall right off. Diagnose this before replacing the module as it's expensive, but a part that fails all the time. Good luck.
