2000 Chrysler Grand Voyager gauge cluster out and no spark

Electrical problem
2000 Chrysler Grand Voyager 6 cyl Two Wheel Drive 136000 miles

Have a 2000 Grand Voyager 3.3 flex fuel, gradually having gauges issues a year ago, would go out (no readings on anything) while driving then come back on randomly. Now van won't start, gauge out permanently with a light amber (glow) to the gear select LCD at bottom of gauge. We get 2 shots of spark at attempt to start, then no spark until letting off the key, then one last spark causing a backfire. Plugs are new but gas soaked. Changed out the crankshaft position sensor, coil pack, plugs, checked all fuses, changed out the gauge cluster from working van but same dead gauges result. Also replaced the PCM but to no avail. Wondering if BCM could be culprit. Don't know what else would affect gauge and spark simultaneously that we haven't tried.
