Mike, Try disconnecting the gas line to the cold start injector (just remember to plug the hose before you try to start the car!) Seems the most common failure mode for these cold start injectors is to leak gas into the manifold when they shouldn't. Disconnecting the electrical connector won't help, it's probably a mechanical leak inside the injector. In other words, it can't keep shut when it should (when it's told to by the electronics). One more thing: Don't disconnect any part of the fuel system while it's still pressurized! Either bleed the system per the manual or let the car sit for a while, long enough for all engine parts to get stone cold and the pressure to drop somewhat. Either way, make sure your workplace is well ventilated, no smoking and so on and so forth...
