I have a MK3U and have a weird issue. The run buttons are not working in gameplay, but in switch test mode they "bong" but they don't light up in the test. Everything else works just fine. I must be missing something simple here.
 
Move the wires from the Run button to LP and the LP wires to the Run button. Verify the issue follows or doesn't follow the wires. If it does, you have a PCB or wiring issue. If not, it's likely a switch issue.
 
When I put the board back in the cabinet I put p12 on one pin over. I blame the dark bar and my poor vision. Works like a champ now. But I wouldn't have even thought that was it without Zenomorp's comment.
Thanks for looking at it

Nice to hear you got it solved! I've had the same thing happen with other games as well with plugging stuff in one pin over for controls. Happens to the best of us!

another weird input anomaly I've experienced, UMK3 at work is in MK1 cabinet with the slide on/off test switch. it's possible to enter test mode and exit with the switch still on, random buttons will not work in this state.
