Hi, I have a MCX 180 nytro that will not run with the MCX box plugged in. When I plug in the stock wiring it starts and runs no issues. When the box is plugged in it rolls over but does not fire the injectors. I sent the box back to PG and they sent me a 190 box, I plugged it in today and no go??? So wondering if anyone has any ideas to help. It does not throw any codes and shows no codes in the diagnostic menu. Thanks in advance, my first post but have been reading on here for few years
