it is physically damaged if injectors were squirting with key on, not running.

one wire is power ,key on, see my schematic ,its clear.
so if you have a connector with fryed wires in it , it will cross over ( give time)
and will squirt for ever.

you need to find out where the damage is . and correct it.
IMHO all you did is wiggle it and temporarally fix it.

look for copper strand frays .

I checked wire bundle and found no damage.Im pretty sure problem was corrosion or water. wiggled bundle to check when i was taken conuity check no problems found.when i had problem i had cotinuity in right wire and high resistance in another.after i plugged together a coupple times resistance disapeared.I felt it was a problem waiting to happen again so i checked it out pretty good.thanks for the concern

so its is not a leaker but a dead injector.?
Corrosion = dead
shorted they leak.
1 dead injectors cause that cylincer to pump just air.
this air hits O2 sensor.
then
O2 read LEAN ,
and then ECU throw more fuel and all cylinders flood.

these cars (all EFI CARS) are demons. in this way.

you must have had a huge leaks antifreeze or something these connectors have gold contacts and never fail.(nice seal too) I think its a case of collatoral damage, id inspect them all for contamination. The seal needs to be lubed with Silicon grease.
this will keep fresh and supple and seal well.

thanks for share, very interested in injector fails of any kind.
great diagnostic work btw !!
cheers.

PS: this is the Achilles' heel , of EFI.

ECU assumes all cylinders fire. if one more dont?, it slams its face into a left hook.
ie: it does the opposite and wrong thing. throws more fuel.
