I was replacing a GFCI outlet, and was almost done when I nicked a wire and caused a short. The existing wiring was 14/2, and there was no room for error. So I spliced in a length of 12/2 and wired in the outlet. Tested it and worked like a charm. Once I sealed up the wall it wouldn’t work. (of course). So my question is was it the spliced wire that is causing the problem ? The GFCI that feeds this replacement is the one that keeps tripping. SO is it the wiring or something else?

look at the 12 to 14 connection....
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming
WOW!!! What a Ride!
Forget the primal scream, just ROAR!!!
"I was replacing a GFCI outlet,"
"The GFCI that feeds this replacement is the one that keeps tripping."
There is no reason that for one GFCI to feed another one.
Or do you mean a upstream GFCI protecting a regular receptacle?
The GFCI that is upstream is feeding a recepticle.
If the GFCI is tripping it's not a bad connection, but a short of some sort, or you miswired the GFCI somehow. First guess would be that you installed it backwards.
(I am curious as to how, in the process of replacing an outlet, you could nick a wire so badly as to cause a short.)
If I read your post right, you did the splice and then sealed up the wall???
That is a big no-no.
You didn't leave the splice laying in the wall did you?
Pardon my fat fingers.
