When you say turn it on, meaning when you turn the switch nothing comes on or it won't start?

Like when I put the key in the ignition and try 2 start it, it sounds like it wants 2 start but doesn't. Cause once I put the new optispark on it would start up right away like nothing. But then like 2 days after it won't start. I'm thinking it could be a loose belt?

may be a fuel pump relay same problem for me right now. was messin with the little box where all the power runs through the little red box under my hood shot some sparks off it and then when i would turn the ignition over it turned over a couple times like it was gonna start then no more combustion. Also since you said you recently changed an opti check the ends of the harness and make sure theyre connected good.

Pull a spark plug wire off your spark plug and put any spark plug in the end that wire you pulled off your spark plug. Get someone to crank the engine while you are watching the spark plug and see if it is getting a spark! If not then you have a problem somewhere along the lines of bad opti or rotor button, or coil or icm. There are ways to go about finding out whats wrong you just have to start pursuing them. If you need any help pm me and I can try to help you find out where to start.

Also try checking all of your fuse's could have blown a number of different one's like maybe the injectors or something.
