Well of you've seen my recent thread about injectors squirting, at least mine isn't as bad as yours. Those injectors cannot squirt fuel unless the air plate metering arm is deflected so far as to open the fuel delivery ports in the fuel distributor without engine vacuum pulling the arm down against the control pressure established at the WUR. Two possibilities come to mind: Either someone adjusted the mixture screw down way too much (in which case you'll hear the injectors squeal with ignition on but car not running...provided you pull the metering arm plug to the safety switch to force the pumps to run), or your WUR cold control pressure is way out of whack, i.e., too low, so when you crank the engine and the metering arm deflects...it's deflecting too much and dumping in too much fuel. The amount of fuel you're describing is a boat load. Best guess is something wrong with the WUR. Do you or your wrench man have the gauge setup to check system and control pressures?
Of course the other place to look is ignition, which might be more probable. How is your spark coming off the coil?
EDIT: One more thought might be the fuel return line to the tank. That's an integral part of how the WUR controls pressures. People on here need to chime in with more knowledge than me.
