car won't start

ok here the story.when i first got my car like 2 weeks ago it was running,until i changed the wiper motor.after that i could not start my car.I hear a click from the starter when i turn the ignition on,so the starter is good.changed my spark plugs,alternator,and spark plug wires.now it still won’t start.I noticed the spark plugs are not getting any spark and my signal lights plus my cluster light goes on and off.could i have a bad ground somewhere or need a new ignition coil?can someone come take a look at my car?will pay for your trip and have beer or pizza. located in maple jane and major mackenzie area.

bad ground sounds like, had it before also
