hi everyone. i have 05 zx6r with about 17k on it. I just changed my fuel pump, and the bike doesnt start... it used to work perfectly before. i put the old pump back, and still nothing. i checked the fuel pressure, spark, battery voltage. there is spark, injectors spray fuel, and the battery is fine also. the bike cranks fine, but just doesnt start. i spent 3 days working on it and trying to figure out what the problem is. when i sprayed starter fluid inside the intake, it started fine. i just have no idea what it is, because since there is spark and fuel, it should start. Please help me out here, any input will be appreciated. Thanks a lot.
