Thanks for the input guys. I will have it checked out but its hard when it won't do it all the time. I'll search around FF and see if I can find anything. I was thinking about it and maybe backfire isn't the best term, its not like a loud *bang* its more like a loudish *pop*. Basically I turn the key, it keeps turning over but doesn't fire, I let off the key and it goes *pop*. Second time fires on first turn over. And again, only does this when its a hot start and not on every hot start. @Trough Lolly - Is there a best way to check fuel line pressure?
