I think I found the source of the ticking under the hood. Looks like it's coming from the injectors. What would be the cause? Did they all go bad, or is there a low/high voltage/amperage issue? Other then the tick, the car idles and revs just fine.

I highly doubt the ticking is from the injectors. Injectors will click when they fire. You can verify this with a stethoscope or a screwdriver against the connector. Ticking will most likely be exhaust leak, spark plug wire arching, bad lifter thats not pumping up.

I did use the a screwdriver to listen for the tick. Only ticking I hear is from the intake right by the injectors, and on the injectors themselves.

I'm gonna say you got a lifter ticking.

All injectors tick somewhat. It's what they do. You should get about the same noise from all of them.

My injectors have always had a tick, and when you rev it up the sound chanves with rpm. This is normal.

I guess the reason for my concern is that the tick in the Pontiac is much louder then what I have in the Buick.

Mine tick pretty loud but it's of no concern to me, car runs just fine.

You can hear them clicking over the engine running?

Yes

I realize that, but they are much louder then the injectors in my other LT1.

My old multitec's were loud, I upgraded to 32lb bosh gen 3's way quieter. I had two that were going bad knew do to resistance check. I know it's possible to here them fire over the engine unless you have open headders.
