Leaky injector

I believe I have a leaky injector. My car stalled on me 2 times now, both times I was sitting at a stop light and after a slight acceleration and letting off the throttle it stalled. The first time it happened I could smell gasoline (the tank was also nearly empty). I did some data recording but could not reproduce the problem. I would attach the files but it says they are invalid type... Later I checked my catch can and I believe there was some gas in it as well as the dip stick smelling slightly gassy. There are no engine lights and it otherwise seems to be running OK.

Where do I go from here to be sure and find the leaking injector? I have seen videos of listening for the ticking and checking the ohms but haven't done that yet. I know that can help find a "bad" injector but would it find a leaking one? Any help would be appreciated!

Also the engine was rebuilt a couple years ago with a Trilogy (60lb injectors) tuned by Lidio.

If it's stalling and your smelling gas I'd look into the FRPS.

I only smelled gas while waiting at the stop light just before the first time it stalled.
I checked for any fuel smell in the vacuum hose attached to the FRPS and there was none. I also took the FRPS off to try and blow through it and I couldn't. There didn't appear to be any pressure in the rail when I removed it but I haven't started the car in over a week now. I have a fuel pressure gauge on the way.

check your air idle valve. It can cause stalling.
