i was doing a tune up on my 96 integra ls. i pulled the spark plugs out changed them, pulled my distributer cap off and was going to change my rotor but i couldnt get the screw out so i just changed the cap. i put everything back together and it will turn over but will not start. i put everything back to the way it was with all the original parts and it still will not start.. does anyone know what could be wrong?
