Evcon furnace trouble shooting model DGAT070BDC - ignition module or gas valve

I have checked a couple parts already and need some direction as to the place to look. I have an evcon furnace model DGAT070BDC. I was having trouble with my booster motor running constantly even after the finish of a heating cycle so I took both limit switches and the booster relay in to a furnace place to have them checked. They said my relay was bad so I purchased a new one. They checked my high limits both were good. I put it back together but when I started the process I had not flipped the breaker off yet and had some arching on one of the relay wires. I then finished assembly and now my furnace does not light and the inducer still continues to run. I did take the inducer -booster motor in for a bench test and the cetrifugal switch is fuctioning properly. Not to many parts left to check and could use some help. Im guessing its not the ignitor when I put the testor to either wire it is not energized during the first 5 min. Im thinking it must be an ingition modual or gas valve? Hope you can help. Thanks Ted
