Id also check the ground wires. If it's not grounded properly somewhere, it won't fire. Everything comes on like normal just no ignition. I had a bad connection right at the battery once and it wouldn't fire. Luckily I started with the easy stuff and found it right away. But there's lots of places grounds go to. Not likely it's a break in the wire somewhere but it is possible. Hopefully you won't have to get that far. Good luck!
