Check the wiring on the connector plugs make sure all the wires are the same color on both sides, red to red blue to blue and so on. I had the same problem After replacing a stator and just plugging it in,after two weeks a new cdi and coil i noticed there were two wires transposed.
Hi, much more info needed.. Year, make, model. switch on & not defective? battery fully charged? Safety switch right handlebar in proper position? and functioning properly? Switch on clutch or kickstand shorted out or bypassed? Generaly speaking the wire to the plugs comes directly from the ignition coils.Power can't get to the plugs if the coils are not getting power. If it is a vintage bike, it may be that the ignition points are burned out. On a newer bike the stator/reluctor assembly may be acting up/defective/shorted out. Not an easy problem to diagnose over the computer. Good Luck
There are some possibilities which you
will have to check in this case:-- 1) First of all check the power and
voltage to the battery. With meter it will show exact 12 volt if the
battery is charged. If the voltage is less get the battery charged at local
auto repair shop. If the battery is internally drained and not getting charged
then its time to replace the battery. 2) When you crank the car do you see
spark coming at the spark plug? If no then its time to check the spark plugs
and coil pack. If the spark plugs are not worn out and looks new then its time
to check coil pack. The spark plug gets power to spark from coil pack. 3) The other thing to check in this case
is the starter solenoid of the car. If the battery is charged and you start the
car then it gives power to the starter to start the car. But if starter is
faulty or not connected properly then car will not start. 4) The other thing to check in this case
is fuel in the car. If there is fuel in the car then check the blockages in the
fuel pump if the fuel pump looks proper then check the fuel filter above the
fuel pump. 5) If all the above possibilities
mentioned above checked out OK/perfect then it’s a electrical issue and
the wiring's in the car needs to be checked. The car gets
power from the battery to get started. so the wires from battery needs to be
checked one by one.
Thanks. Keep updated for any more query. You can rate this

There are a # of things that can take your spark out, first I would see if you have power to your ignition coil (100V+). If none there you need to isolate your ignition switch (unplug it or take it out of the equation) and jump your starter solenoid manually or try pushstarting the bike. If still nothing check for voltage going into your CDI box, if none check for voltage out of your stator (over 100V) and your trigger or pulse coil (over 3V). If you find voltage at the stator and not the trigger replace the trigger and vice versa. If there is voltage for both replace CDI box (but be cautious to verify good ground for CDI box and ignition coil). If you find voltage out of your CDI box (over 100V) replace your ignition coil. Good luck!
