The LPG wil not feed the furnace burner, unless the motor runs. When the motor runs, the air moves a "sail switch" which in turn activates the LPG valve.
For what ever reason, your motor is not running. It could be the relay, it could be a disconnected wire, it could be a bad motor.
Pulling the furnace out for a bench check, should answer the question.
