No starter operation? Why is my engine not cranking over?

There is no power the battery wont even work I just brought a new one and I checked the fuse its fine

The car was operating ok. Parked in a lot at work.
When attempting to start a few hours later, sounded like the starter solenoid & gear failed to engage the flywheel (sounded like the starter motor was at full speed).
Pulsing the starter with the ignition key and tapping the starter motor did nothing.
Towed to a garage. They diagnosed that the starter was bad. They installed a new starter which did not fix it (same symptom).
Can't believe a starter motor 12 years old and a new one (not a rebuilt) have the same defect.
Cracked or otherwise defective flywheel?
Timing chain problem?

In Lady Lake, FL so cold weather is not involved.
Engine oil level is full.
No water or oil leaks.
No mechanical noise before this happened.

My 1996 ford explorer won't start, not even a door chime, battery is good, alternator and solenoid have been replaced, what's the problem? What do I do next?

My 1996 Ford Explorer is not restarting after say, going to put gas in it. I have to pop the clutch to get it going. The starter has been rebuilt (new selonoid (sp?)), The ignition switch has been replaced, and now the clutch switch is being replaced. Are there 2 clutch switches?
This is a great old car, I had it built for me.
Thanks for any help in understanding this.

No, the starter is rebuilt, now it was another problem. The mechanic replaced the clutch switch, and he replaced two things. I was asking if there are two clutch switches, the car is now starting up every time.

My car doesn't want to start up sometimes after driving it somewhere and stopping for a few minutes. If i'm going to the store or while my boyfriend is waiting to pick me up from work, driving THERE is no problem. It's if you stop the car, turn it off, and let it sit for anywhere from 5 to 30 minutes before starting it again that it starts to act ornery. And then it may not want to start for another 30 to 60 minutes. It doesn't always do it, but it does it enough to be annoying. And there's always the concern of one day being stranded somewhere when the car doesn't want to turn on at all.
I've described the problem to some people, and they seem to think it's starter. I don't know though because it's not as if the car isn't turning over. That's the thing: it'll turn over but not want to stay on. Giving it gas doesn't seem to work, heck, sometimes it's not on long enough for you to give it gas. But before I shell out 150 for a part I don't really need, does anyone have any other ideas?
Thanks,

I was driving and the speedometer, radio and blinkers stopped working and then the explorer died. Now it will not start but still has power. When I try to start it the car a repetitive clicking sound comes from the engine but it will not turn over. I was wondering if this is the alternator or starter that needs replaced.
