just tried tuning up (cap,rotor,plugs,wires all oe from the dealer)100%sure everything is on properly and my car won't start even tried putting the old stuff back on ,my car is a 93 si w/95 b18c1

 

Did you put the spark plug wires in the wrong order onto the dis. cap? Because if it's not correctly plug into the corresponding hole on the dis. cap, the car will not start. If that is correct, then double check to make sure the plugs, and dis. rotor inside is tight. Should be either of these two.....
