Pentair minimax 100 ignition lockout

I recently posted. I have power to the system. I see that there is a spark to the ignitor for 4 seconds while I hear gas going to manifold. No pilot light. I must turn thermometer switch to midway to get spark. Then shutdown with 3 flashing lights to LED indicator on Fenwal. Smell gas after I turn off switch and shut gas valve off. Seems like gas and spark are there, but no flame up. System is entirely clean of debri. Just replaced transformer and heat fuse prior to starting. Also checked all wiring (no chewed or burnt wiring. All wires are hooked up correctly). Any suggestions?

gas + spark = flame so there must be something with spark or gas. If you are getting a proper spark in the proper place and smell gas, it might be your gas line needs to be bled.
