Are you sure the new coils were mounted in the correct orientation (this side out, or cylinder side). The coils can be installed upside down and they will not work.

Make sure there is a good ground between engine block and coil laminations.

Make sure magnets on flywheel are good.

Good spark will almost be invisible, but you should be able to hear it "POP" when it jumps the gap on your tester.
