This procedure usually works:
·Check the battery cable connections:
Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine. Make sure the positive cable, makes a good connection at the battery and at the starter.
·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.
Check the ignition system with a timing light to see if you are getting spark to the plugs.

if you replace the alternator im sure it will be fine while your driving the battery is not getting charged so thats the only thing that it could be

the starter should be replaced. The solenoid is kikcing the pinion out but there is no contact being made to turn the starter motor. I have the exact same truck and before i changed the starter used the old starter tap trick. Tap the starter casing with a hammer and it should start turning again. hope this was helpful for you. Good luck.

this is a stupid idea but one of my co-workers have a 98 explorer and she lost the chip in her key. after that it still wouldnt start turns out the anti-theft kicked in and they had to reset the fuel shut off switch. your battery replacement maybe did the same? not sure where your switch is but hers was up under her passenger side floor board up front somewhere around the kick panel it was a purdy red button

When its hooked up, you should be able to put 12 volts on the little stud on the solenoid and it should start. One large stud will have 12 volts on it, so just jump it right there. Did you get the wires in the right place. The solenoid should have 1 large wire going down to the starter. Be sure the battery cables are clean and tight ( both ends) Check battery voltage when cranking, should go to 10-11 volts. Check voltage between negative terminal on battery and engine, should be ZERO when cranking. The solenoid has 2 large studs, make sure the battery positive wire and all the other wires are hooked to this stud, the other large stud should just have the wire going to the starter.

You said you tightened the battery cables, did you check the other end of the negative where it bolts to the engine. When you tightened the cables you also used a battery brush and cleaned the posts and ends?
