Honda Accord won't start after tune up

After it wouldn't start I put the old ones back on it and now it still doesn't start everything is right there on top of the motor and nothing is there to get in the way to even bump to knock loose.

Check the firing Order FIND # 1 ON THE DISTRIBUTER CAP SEE WHAT DIRECTION THE ROTOR BUTTON TURNS WHEN YOU BUMP THE KEY THEN FOLLOWING THE FIRING ORDER PUT THE PLUGS ON IN ORDER IN THE DIRECTION THE ROTOR TURNED C/W OR CC/W

See that's what I can't understand I did one at a time so I couldn't get them Crossed up that's why I am so confused and it was running fine right before I changed the spark plugs and wires when it happened I put the old ones back in to see if I had gotten a bad set of wires and it still wouldn't start

Pull a plug, connect it and lay it where it is grounded. Crank the engine and see if it fires. Put it back and squirt some starter fluid (ether) in the intake and see if it tries to start. Check the timing with a light. The distributor may have been moved. See if the rotor is in good shape and making contact with the the rotor. Engines these days have computers and you may have to check it with a plug in meter or google how to check engine codes with a paper clip.

I HAVE A 2000 HONDA ACCORD, HAVE CHANGE THE DISTRIBUTOR CAP AND ROTTER .IT STILL HAS THE SAME ISSUE, SOMETIME IT STARTS AND SOME TIME IT WON'T
