There's not much to this ignition system. If you aren't getting spark, it's usually either the coil or the PCM.

Verify there is battery voltage to the positive side of the coil (Grey) while cranking the engine. Note: It is normal to have 0 volts on this circuit with the key "on".
Attach a test light to battery positive, use the probe end of the test light on the negative side of the coil (Black/Grey). Crank the engine over and the test light should be flashing on and off. If it is blinking then replace the coil.
If the test light is not blinking then it is a wire problem between the coil and the Powertrain Control Module (PCM), or a bad PCM.

the light turns on when I use the test light to the negative side of the coil. where or what is the PCM
Expert:  Jared D replied 1 year ago.

The PCM (on this vehicle it's called the ECM) is on the firewall. It controls engine spark in place of a distributor.
