14 is specifically...? Inj, #1 ckt?

When you have a code you need to stop and think about the specific wording and how the ECU would determine what it 'thinks' is wrong. If it is "#1 Injector ckt or injector fault" how would it determine that? Power to the injectors is common to all, or at least three (each bank.) The ECU grounds the injector when it wants it to function. That means the ECU would expect to read voltage on the ground circuit of the injector until its driver grounds it, then it would read -0- volts. Now maybe it is seeing ground on that injector circuit all the time, even when it isn't commanded. That would mean you have a short to ground on that individual circuit and when the harness is attached to the injector it would flow, non-stop.

Obviously the easiest (read:lazy) thing to do would be to unplug #1 injector and start the engine. A misfire on #1 would be expected but the excessive fueling issue should not be present. Of course, I hope you would check the injector harness for a short to ground. These cars are aging and it doesn't take much to knock some insulation off. Also, you should know better than to introduce too many new items at one time, doing so creates a potential diagnostic nightmare for yourself.
