Are you getting power to the coil? Have you checked all main fuses under the hood?

Check the coil to see if it is the problem. It sounds bad.

If your parts work on his car and everything is good, then you need to check wiring to the PCM as well as the PCM itself. Make sure nothing is corroded, check continunity in the wiring to the coil to make sure there is no internal wiring damage. Check the plug to the PCM for corrosion, pins pushed in.

The PCM is the power control module. It runs just about everything. As far as the timing, you would still have good spark just at the wrong time.
