I think I may have suggested testing for compression on your older post. If you have zero power to any other components such as windows, radio, gauges, etc, you may also have a bad BCM or body control module.

Solved my problem on 94 Dodge B3500. Van would crank but no run. No spark to distributor, replaced coil, checked PCM & ECU & TCU & BCM & TCM & ASD all of which controls ignition spark. Finally checked all the fuses (box & in-line) and connections since a 94 van has many splices all to no avail. And then I spotted a dangling wire with a cap on the end way back behind & under the alternator on the front of the engine. Very hard to see and get to. Plugged it in and it started. Bingo. A 4 day adventure had ended.
