Swith and engine flood, help

Alright I have my switch to turn on my microtech LT8S hooked up to my headlight switch. Is that ok? Because when I crank my car it seems that I flood it with fuel and then it backfires, is this something to do with my wiring or my CAS and my spark plugs not working right together?

Put a new set of plugs in it.
Sounds like your wiring is bad? Why is the PINK wire connected to your headlight?

Pink is the switch so I chose the headlight since they literally are controlled by a switch and the location was easy. I also did not want to mess with the wires leading to my ignition barrel. Should I hook the pink wire elsewhere? The plugs are brand new as well as the wires. The microtech starts fine with the turning of the headlight switch on the first or second position. When I crank the car the fuel pump turns on, the primarys are firing, I can hear the fuel pump pumping the whole time I am cranking (and when I turn ont he switch it turns on and pumps for like a few seconds), the spark plugs are indeed firing as I checked all of them during crank (and also when I turn the headlight switch they fire). The car feels like it is going to start but it doesn't. When I poured down some fuel the intake manifold into each runner then I crank the car the car almost starts, it produces exhaust even, and then after a few cranks the motor just goes back to cranks as if it burned all the fuel and no longer produces exhaust. But if I turn on the headlight switch (to turn on the microtech) and then start to crank the car the car will crank (without pouring fuel in teh intake mani to the motor) over a few time like 5-10 then a loud back fire will occur. Weird cuz wouldn't that imply that all my fuel isn't getting burned (like getting to the exhaust mani) then all the excess gets burned all the sudden causing the backfire. But thats weird cuz when I put fuel down the runners it doesn't do this. I'm real confused

I'm checking the timing today. I'm using a map that u gave me. It is for a streetport (mazdatrix templates I believe) with walbro 255, 550cc primary, and 1600cc secondary. I'm using a hand controller with the microtech, just so you know.
