When you try to start the car the starter will first click then if you hit the key again it will turn slowly then whirl then finally start i think its bad spot in the starter but not sure?

Sounds to me as if your starter is dead. Do you hear a click every time you turn the key? If so, then it is your starter. You can try hitting it with a hammer or something hard and try to turn. Chances are it will turn over but sounds as if the brushes are dead.

Obviously you had a fuel or ignition problem. If engine turns over then no need to replace starter. Now it sounds like starting problem has occured. Is the battery fully charged?

They only have 2 bolts holding them in. Unbolt/unclip the wires from the starter and then remove those 2 bolts. Replacing it is the same process in reverse.

If car wont start and clicking sound is heard this is a battery related or starter related, if your car battery is in good condition (which I think it was) then the problem is your starter, have it check to confirm.

i had same problem it is your cam positioning sensor

possible dead starter -- see if you can hit starter a few time and try to start car.

battery is low on voltage as far as the locks clicking, you could also have a starter issue, try charging the battery first

If Its A Manual Can It Be Kick Started? If The Dash Lights Are coming On And Dont Dim When Fully Charged Its Probably The Starter Sticking . If You Hook It Up To Someone For A Jump Start Does It Start? If No Its Your Starter.
Next Time It Wont Start Try Hitting The Starter With A Hammer.
If That Works Its The Starter.

Lots Of Things To Narrow It Down And Be %100 Sure Its The Starter

Starters and starter solonoids are a big big problem on high mileage explorers Try to tap on the STARTER with a hammer not too hard there are magnets inside and you will crack them hit it firm though. Do you even get a 'CLICK" when you try to start it?
