Propane Furnace won't ignite

[OwenTrail]

I have a older 1996 TM with a Suburban Gas Furnace. Was working fine the last time I used it this spring, but when I went to use it a week ago this fall, it would not ignite.
The thermostat is working a-okay, it will kick the fan on and then can here the igniter try to light the gas, but with no luck. Any direction on where to track down the problem will be appreciated.
All other gas appliances work, Stove and water heater.
The unit is a Suburban furnace, model #NT-16SE
