New battery, still won't start

My 89 Firebird (V6) broke down and I recently got a new battery since the old one was bad. I put it in and it wouldn't start for several moments and many attempts. In trying to start the car, I noticed the battery gauge was in the "dangerously low" area. I took it in and exchanged it for a stronger battery that I've read is more appropriate for the vehicle. The battery gauge has gotten higher and closer to the normal range, but still hasn't gotten there and won't start the car.
What could be causing that? Is it something the battery is wired to not getting the current properly? I know it can start, but it hasn't done so easily. Once it finally starts, it can be started back for about an hour after untl it cools down. Drives fine otherwise.
I just need to figure out what this is before I can move on to finding the running problem it has.
Any help would be greatly appreciated.

Car Is Not Cranky . . . . SO I AM !!!!!!

Connect a voltmeter across the M terminal and ground.

Make the leads long enuff to take the voltmeter into the cockpit.

Under normal circumstances you will see about 9 volts on the meter while cranking.

On the occasions the starter fails to crank note the voltage.

The voltage will tell you what the problem is and what direction to turn.

If it’s about 12 while you are trying to crank, but the starter is not turning - the problem is in the starter.

If it’s under 8 while trying to crank - the problem is excessive resistance in the starting circuit.

Therefore if it is in the starting circuit you can move the probe you applied to terminal M at the starter, to the positive terminals at the solenoid, then keep moving up the line till the problem shows itself VIA increased voltage.


Happy Racing!
