If you can, remove the pipe from the Y pipe, and unplug your injectors. Pull it several times with the key on kill switch up, this will clear the case. Assuming you have new good gas in it. When the crankcase and pipe load with fuel they are impossible to start. Once it starts to idle, plug your injectors back in and slowly push the pipe to the y pipe to let it start to clear out. It has happened to me a few times. Reinstall exhaust springs after it is cleared up. If that isn't it, then start ohm testing as stater, tps... checking electrical.
