There is no power to anything, the dash lights even quit. Problem started after I checked the fuses and did a reset the computer (PCM?) Sequence. I believe that the ignition relay or starter relay switches were part of the initial problem of the control panel gauges flickering at the bottom of the indicator and making an audible rapid clicking sound. Earlier this summer the guys reset the computer by pulling either the ignition relay or starter relay switch and waiting a period of time, then replacing it and voila! Problem fixed. When I tried it everything went kaput. Guys are no longer available to help.

If you lost power to everything, make sure the battery is good. Also, I'm not sure how pulling either of the relays you mentioned would reset the PCM. That makes no sense to me. If the battery is good and fully charged, make sure terminals are clean and tight. Also, check main fuses under the hood in the power distribution box.

Let me know what you find.
