Need some help fast!!
Ok, tonight we went out on our boat. Its a 2002 Supra Launch with an Indmar V8 (a 360 I think). Well it has throttle body injection, like the older 350 chevys. Well with the key on acc. (motor off) it wont stop spraying gas out of the jets. It acts likes its running and feeds it fuel, but the motor is off. What gives?

On each injector there is a white plug lookin thing with a few wires runnin to it. Is this what supplies power to it? Also commin off the back is a vaccuum line that runs to an sensor that says pressure sensor. Any corrilation? I really dont know much about throttle bodie injection. What is the ECM and where would it be located? How could I check to see where the injector is shorted? I dont really know where to start, and the boat is at my dads (about an hour away) so I cant walk outside and look. Were supposed to take the boat out 4th of July weekend so I wanna get this fixed.

Sounds like the key switch is supplying power in the ACC position to things that should only get power in the RUN position.
-Trace it!
This could be a bad key switch, or corrosion on the back of the switch, or in a connector.
