I have a 2005 Hayabusa that started hesitating when hot, then stalling when hot, then turned into a cranks but no-start situation. The FI light never came on. It has spark, but when everything is hooked up there's no fuel injector pulse. First I replaced the Cam position sensor, then the crank pickup and stator, then the computer. I accidentally disconnected the vacuum hose from the MAP sensor and it tried to start, started briefly, and stalled. Then I got it to idle, very poorly, with the MAP sensor disconnected. So I replaced the MAP sensor. Same thing. All vacuum lines seem to be accounted for. If I hook up the map sensor, it stalls immediately. Any help would be appreciated.
