edit: 1995 Nissan 240sx ka24de
1.) Car has power (interior lights etc.) I go to turn the key to start the car then I hear the motor turn almost as if the battery is low on power then I just get "click click click click" It'll do this everytime. It seems that it only did this once I replaced the battery terminals...
side note: I got the battery tested at advance auto it said it was good and took a charge, then I went to start the car and the same thing continued.
When I have the key turned to the "on" position and have the radio on or lights or something the power will cut out then come back on right after it cuts off.
What motoman just said, grounds. The flimsy braided lines the factory uses has a limited lifespan. You can make a few of your own out of some ring terminals and extra speaker amp wire (Everyone has some extra 8 gauge lying around right?) Run a few from somewher on the engine to somewher on the body or right to the negative terminal. make sure your connections are clean, like sanding paint off the body if you ground there.

4.) When I start up the car it wont always stay on unless I hold the gas pedal down for a second or so. After that second, it'll idle fine.
These two: Search for threads on adjusting the IAV. Read a few of those and try some of the suggestions.

thanks
Bad exhaust manifold gasket? Hesitiation is probably something else.
Oh, before you crack into the IAV, make sure all you vacuum lines are OK and there are no leaks.
