It sounds as though you have an issue with the ignition switch that needs to be addressed first.

Check and test the ignition switch, fuel pressure if its within specs and verify the valve and ignition timing-

Yes, it could cause the no start condition. The switch may not be sending the signal to power up the ignition primary circuit.

The no communication issue is probably a loose connector pin or broken wire.

You have engine turning over and spark, but it's not starting?
Check all fuses and relays.

See images. Test continuity on the lines to and from the data connector.
