Goodman Natural Gas Furnace Problem

Our natural gas Goodman central air heater won't start on the first attempt much of the time. The inductor fan starts, the starter element heats up and glows, but often the gas won't ignite when the flow begins. the heater is set up to try 3 times, and often won't even start after the third time. I can manually start it by holding an extension lighter where the starter element is, but this gets kind of tiring.

Any suggestions?

Thanks!

Which shows the gas valve is opening, but the glow of the ignitor just is not working good enough. You can ohms test the 2 ignitor wires. They had on a popular syndicated weekend radio show, this weekend, that the rule of thumb is between 50-100 ohms is okay for most ignitors. Some new ones are even less. But over that, you can have a glow that is not quite enough to set off the gas in time, so the valve shuts back down. If you haven't got a multimeter, you could just take the chance and buy a new ignitor. They are not that much. Cheaper than a furnace man coming out and knocking on your door.
