Other sea doo keeps pumping fuel into cylinder

[callmefinch]

i know this isnt what people generally post about but im hoping to find a fix for the problem, my sea doo fuel pump keeps pumping fuel into one of my sea doos cylinders almost locking it immediately. im thinking one of my injectors is stuck open and the pump isnt reading any back pressure so it just keeps pumping.
any info helps thanks

what kind of seadoo?
Had an RXT 215 here with a bad eCU causing fuel pump to pump constant.

Well for an injector to dump fuel it could be stuck, or the trigger side could be shorted to ground, or the ecu could be bad and holding the injector open. Is it only one cylinder? Maybe unplug each injector 1 at a time and see if unplugging it stops the flooding of fuel, if not it's prob an injector issue, if it stops with the injector unpluged then suspect a wiring or ecu fault

well as soon as i plug the key in the fuel pump kicks in and it kicks on consecutively about every 5 sec. i pulled both plugs and turned it and the front cylinder was just spewing out fuel. i tested the psi and it was maxing out the sensor. it wont turn when both plugs are in but when leaving the front plug out and the rear plug in it will turn and fire, but with the opposite, the front plug in and the back plug out, it will not turn. it sat for about a year or so i just got a new starter for it and my dad was the first to fire it and appearently the fumes exploaded and it blew the exhuast house off the back. i ran it 3 times with no issues after that and now it does what i described.
