weird Science
after a short ride last night , I used my ignition switch to turn off the engine and tun it back on so I can see my garage door keypad .using the headlight ,after I open the door , went back to my bike ,I smell gas on her , start her up . with no problem , then put her on the jack stand . snipping around her , checking. for leaks nothing, so I was so curious ,so. I turn the ignition. back on, kill switch off this time , nothing happen , turn the kill switch on , I heard the fuel pump working then it quits . and suddenly gas is coming out from the intake .WTF I say ,,, then suddenly the pump came alive. and stop. after that ,,I heard a pulsing noise under the tank . I turn the ignition off . grab My Ear scope , turn the ignition back on . The weird. noise is coming from one of the injectors .. it's sounds like openning and closing, like a heart bit . ,,,,but the engine is not running.,, WTF,,, I say again . what is going on ,,,, .sorry for a long post .. it's a 07 EG.. no tuner ,, just SERT Download..

Injectors sound like that. There is a solenoid actuated poppet valve that cycles every time it sprays fuel....The fuel pump will start up then shut off when fuel pressure builds up to the operational pressure.........You may have a stuck injector though!
I tried to start my bike , but it won't . . and it still doing same thing. I took the spark plugs out . and found out the front was so wet with gasoline , rear is dry .do I need a to replace my injectors . or only the front. ? pls. need advise. thanks
I did try to start it. no start,, and. yes it's still doing what happen last night

1.) year and model info would help
2.) prepare for an oil change, you may well have raw gas now mixed with oil- you want to change that before you run the motor.
3.) the pintle in the injector can become stuck through wear or a spec of dirt, it may need replaced. If the injector is fine, but the ecm is telling it to open ( this can be seen by checking with a meter) then you got problems.

I had one injector go bad on me a few years ago. I was out-of-town on a trip. I wanted to replace both injectors at the time but could only locate one locally. I replaced the one bad one at my friends shop and its been fine ever since. They're kind of a pain in the *** to get to, that is why I wanted to do both while I was in there.
Sounds to me like you'll be replacing at least one, but I'd consider both while you're in there.
