Problem my 93 z28 wouldn't turn over after removing the plugs the third cylinder on the passenger side was filled with gas. i removed all the injectors cleaned and replaced all the o rings, and put it all back and went to fire it up and it ran for a second i shut it off went back out to the car tried to start it and once again it wont turn over and it acts like if filled the cylinder up again, any ideas on what this could be?
Empty that cylinder, start it back up, unplug that injector. Let it sit a while, then pull that plug & spin it over to see if that cylinder is full of fuel again. If it is the injector is stuck open, and needs replaced. If you got it unstuck I would not trust it again.
If not, key off, connect a test light across the terminals in that injector plug. If it lights you have a grounded injector wire. The '93 is not sequential so it won't be an injector driver in the ECM.
Good luck.

When i took the the injectors out i replaced the injector that i thought filled the cylinder up. third plug back on passenger side was filled so i replaced the third injector back on the passenger side?
Yes, third injector back is for the third plug back. Don't drive it until you find the cause. Easy enough to see if they leak without driving it. Just idle it between checking it again.

you have some electrical issues if they are all full, sounds like something is holding all the injectors open, sounds like a pcm problem......change the oil NOW, with that much fuel in the oil you will destroy the bearings very quickly
