C to W on the control board now has zero volts. And, again, nothing happens when i turn on the thermostat; no furnace, no igniter, no sounds, nothing. So what is likely to be the problem?

C to w no voltage not calling for heat if c to r has 24v

I bypassed thermostat, and jumped R to W. Then furnace worked.....kinda. So thermostat seems to be problem for furnace not powering up at all. Just need to put in different one.
But furnace is still short-cycling. Burners are on for only a few seconds, and then they go off. And then process starts again. Burners have been cleaned. New valve, spark ignitor, ignition module, control board......................... ????????????????
