Could be a bad spark plug, bad coil, bad fuel injector, wiring problem or a mechanical issue with that cylinder.

Yes, verify that you have spark and fuel on cylinder number 6. If you do compression test cylinder number 6. If the compression reading is low, it won't fire. Just so we're all on the same page, cylinder number 6 is in the back, next to the firewall, closest to the driver's side. HTH. -Jim
