Not cranking over

Yes, the car wouldnt crank, would only buzz. Just wont turn over. Im lost at what to do. And where is the starter crank wire located?

Original problem was that the meters went hay-wire then woukldnt start from there on, now I have good fuses, new battery and still wont crank

It couldnt be alternator.

No They're all fine, didn't check them before.

It won't crank, to even start the car. That's the issue. Can't tell of the light blinks or not. It'll let me
Turn the key and the dash lights will turn on but nothing after

All of the lights on the dashboard come on. I've unhooked and re hooked the fuses and the battery. What else should I try?

Our 2002 Buick Century with 40,000 miles has an intermittent start problem. When turing the key, it is completely dead. Lights are bright, radio will work, seats move, etc. Yet there is absolutely no cranking whatsoever. The ignition switch has been replaced and two weeks later, no crank, no start again. Sometimes, it will start after an hour, sometimes 3 hours and sometimes it takes overnight. However, twice we have had it towed to the dealer because it would not start after 2 days. First time, the ignition switch was replaced. Yesterday, as soon as it was taken off of the tow truck, it started right up.
When we bought the car used, we were give 3 pass-keys which we thought kind of strange. Now, it's obvious that this was a problem for someone else also. The dealer is at a loss. Help

After three more tows to the dealer (after the first two, the car started for them), today it didn't. As soon as it was hooked up to the analyzer, they found that the computer was bad. So, after three months of no-starts, rentals and tows, it is at this moment, being repaired. Hopefully, this will end our used car nightmare. Thanks for your responses.
