My 2018 Z650 ABS turns over but will not start. Brand new, has about 1000 miles on it. I just put on a Yoshimura pipe/exhaust on and started it up, rode up the the street and it stalled. Now it turns over but does not start. I have a Check Engine light indicating a Inlet air pressure sensor Code 12 which was not on until after it stalled(I did not notice it until I went to diagnose the problem). Though it was not on after I installed the pipe confirmed by my GoPro. Now, I have checked everything involved: Gas pump(runs, shoots gas across the garage), spark plugs(sparks good color), it get gas to the injectors but it just does not fire up. I have sprayed B12 over the intake and it stills does not fire. It seems the ECM may be preventing the fuel into the intake. Any thoughts on what could be the problem, greatly appreciated.
