Do these slings fire correctly in switch test? Have you changed out the coil diodes for the sling coils?

Have you repined the connectors on this game?

Ok simple test to see if being caused by sling rubber. Seeing how issue is duplicates easily just pull sling rubber back once it starts. Now nothing is contacting switch. Is it still firing?

I don't work on new pins. Just old Bally's and Sterns. My humble opinion is that his sling rubber looks good. They should be tight against the outside switch. I gap them about 1/8 and make sure the short side of the leaf has the helper spring firmly against the back. I have three of these games right now and I can go look at all of them, set just as above, and have no machine gun firing of anything. My experience is that bad connectors, bad capacitors, bad diode, and bad grounds cause this kind of issue. My humble guess is you have two issues working together against you. Someone installed the capacitor on the switch to get the switch to light up hotter than it needed to be for some reason? Coupled with a bad connection to MPU, connector, or loose solder connections in switch matrix.
