Can't start SR. Got Fuel - got backfire? - HELP!

[2plus4plus0eq6]

Hey there I am just in the middle of trying to get my engine to start. I have been getting some popping noises here and there which I think is backfire. The engine has sat for about 3-4 years since I put the s14 SR into my s13.

I took one of the spark plugs out which was perfectly clean before and now it is black and has fuel on it.

I am not sure If I am flooding the engine, how to unflood it if I am, what start up procedures do I take, etc.

The engine did start for me 4 years ago. It was rough but it did run. I put in octane boost and about 10 liters of 94 octane fuel into the tank. I am not sure if its not going because of old fuel in the lines or what.

any help is appreciated. I have already searched tons for info!! I need help now!!
