Hi, welcome to 2CarPros.

Its obvious but I have to ask, Have you checked the fuses?

Do you have 12 volts to the coil with key on?

Have you checked for a pulse signal?

All fuses good. Power to coil. Thinking it might be PCM.

We unplugged PCM and got spark while cranking motor. Saw online this would indicate a bad PCM.
