Ignition Problem? Or Passlock

I have a 2000 Alero coupe, a couple of days ago my my car wouldn't start after a few tries it finally started. I replaced the battery, at first I thought that was it but a day later it's doing it again. I put the key in and turn it, the car will either click or go dead ( sometimes it will start just fine ), when I release the key the gauges will freak out and go all the way to the right and back sometimes flickering. If I wait for a little bit sometimes it will start fine.

This is probally not a passlock problem.
When you say the car won't start, does the starter turn and the engine won't fire or you turn the key and the starter doesn't turn?
From the description, I'm guessing that the starter wont turn.
First check the battery cables and the terminals...especially the positive one at the battery for corrosion.
Clean it with some baking soda and water.

Sorry for the old bump but my sister is having somewhat of the same problem with hers, the car turns but it wont start, I checked the ignition packs to see if there was any spark going to the plugs and there is spark so far on the 2-4-6 but i havent check the 1-3-5.. can anybody help me out a lil..

You didn't have to bump a dead thread..you should have started a new one....

Anyway, what year make and model car do you have?
What is the problem you are having?
Have you checked fuel pressure?

well is a 01.. as far as fuel goes i can smell the gas when i try to start it. so i think that is getting gas, is there any easy way to check the fuel pressure..

ohh sorry the problem is that the car wont start.. see it turns but it wont start, i dont know if is the starter, i mean if it was the starter i dont think that it would turn..
