Answer 1

Probably your coil is bad.

Answer 2

Make sure all connections on the plug leads are correct, on properly and firm.

Using a proven plug, (doesnt matter where from as long as you know it works, test it on your car?) check for spark on all leads. Make sure the thread of the plug is in contact with bare metal on the engine.

I you get spark on some but not others then it could be the leads or the coils, Swapping leads around will test that.

If you have no spark on any plug at all then trace the ignition circuit and test for power at the coils.
