I'd start by checking all wire connections

EFI or Carb? Did you check for codes? Diagnosing a problem over the internet isn't always easy, but you'll get more help if you tell us what you're riding. Year, model, mileage, mods, etc.

Did you wire the coil correctly?

I didn't take the wires off the coils , just took the bolts out of them to move out of the way so I could replace ignition.

If you moved it I would check to see if you pinched a wire or loosened a connection. Most likely something simple. If it worked before and doesn't now. Double check everything. Switch could be bad but not usually
