Be careful when inspecting the unit, voltage is stored in several places in it, and could cause a serious shock. Take care!

get a continuity meter and check that the coil is not broken also check to see if there is voltage at the wires. becarefull.

You need to get a Meter and trace voltage from where it is, to where it isn't. Maybe there's a Elec Diagram on the U...
could be a few reasons from a bad focus element in the tube.maybe the flyback voltage is changing.could be a small arc somewhere.mostlikely it the tube though.
OK with all the wiring testing, have you checked the voltage at the coils?
And I know you changed alot of parts, but when you changed the coil pack, was the Ignition Control Module part of that?

Is it the correct power supply? Check voltage ratings and current ratings. If Batteries try new ones. Sounds like not getting the power needed.
Hi, thanks for the warm welcome
