Can you run diagnostics on the game? Does it respond to the coin door switches in diagnostic mode? Can you start a game by adding a credit? If no coin Mechs open door and trigger coin switch by hand. You could have bad coin door switches.

Can you get into diagnostics - auto-up/manual down switch down, press advance button twice, all displays light up, auto up switch up displays start cycling 0-9, press advance switch again, you get lights, again you get solenoid cycling, again you go into switch test.
You could be having a problem with the coin door switches, the harness connector to the coin door or the connector on the MPU board for the diagnostic switches (1J4, second from the left on the top of the MPU board.)
