Where can I find the anti-theft device fuse on a 2002 ford explorer. I replaced my battery and starter,had my key tested and still my truck won't start. Can I shut-off my anti-theft and maybe it will start.

POST ALL EVIDENCE FIRST. NOT A EASTER EGG HUNT.
check all fuses first
don;'t have 2 working keyfobs??????
then if the key fails
the cluster (speedo) will glow the security lamp telling you it or the key is failing
not scanning the PCM with a real scan tool means you never learn why/>?
no symptoms told at all, just useless hunt. for relays,
doors dead
car will not start and run.
security lamps glows wrong./?
check fuses
make sure battery is not weak or dead.
12.6vdc is good.
below 10vdc the on car computer brains go WACKY.
make sure battery is good and fully changed first. (both)
have battery load tested if not sure.
then scan the PCM.

look for PATS errors

passive anti-theft system (PATS) security access
Vehicles Built Before 03/2002 have different system for security. most PATS failuers are dealer only fixes.
if just a bad key (fob ) most lock smiths can cure that
for sure with spare 2nd good key,
never just have 1 key or repair costs and explode.

chech and test fuse relay and connections === test battery [load test ] ---test starter and solenoid

If it was the PATS - anti-theft system you would not have any clicking at the starter . You have connection ,cable or starter problems , most likely . Testing the starter electrical circuit doing voltage drop testing .
Starter Voltage Drop
Do you know what a wiring diagram is ? Free wiring diagrams here
http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on engine then under subsystem click starting . Click the search buttom then the blue link. Looking at the wiring diagram I see fuse's at the top ,starter relay in the middle an at the bottom the starter , PCM - this is the engine computer . The PCM will energize the starter relay only if it receive's the correct coded message from the PATS module or which module is in charge of that . So you would not even get a click at the starter ,because the relay wouldn't even be energized . You could possibly have a transmission range sensor problem or positive battery cable to tthe starter or ground cable .
How to voltage drop test starter motor circuit
Test don't guess .

Just unplug it at the alarm itself or cut the wires there. Removing the fuse could also disable something else.

Check the wires good, that go to starter. And the starter solenoid. Clean and tighten all starter wires. By by passing, and starting it direct tells me that there has to be a problem, in wires or ignition system. see if you have power to starter by testing the wire. Sounds like no click on start=no power to starter.

Don't listen to this other guy , he doesn't have a clue ! Check the starter relay ,Transmission range sensor ! Does yours have a anti-theft system ? If so there is a anti-theft relay to check all so ! Also check fuse #24 15amp in the interior fuse panel ! Is this a automatic trans . or stick ? There is no ECM involved in the starting of this vehicle ! If you are unfamiliar with any of this components your better off taking to a professional , before you just replace parts ! you need a volt meter an a good wiring diagram ! You can test right from the starter relay , check for voltage ! Does yours have a relay on the passenger side inside fender ?

Do you have a question ?
Have you tried another key ?

How is that possible,they should have a data
base, such as AllData or Mitchell, etc or
they can not work on any product & may as
well close their doors and go out of business

Your owners manual will explain the system as
far as using it

Any repair shop, should have 15 years experience
with an Explorer,there are a million out there

You need to move on to another shop,don't pay that
one anything

Its a good possibility that the Anti-theft is interferring with the circuit. If you have an extra ignition key, use that in case the password chip in your regular FOB has detriorated.

There is a brake sensor which is on the upper brake pedal. It interlocks with the starter to prevent starting without having your foot on the brake pedal. Check your brake lights for operation. If the brake lights stay dark with your foot on the pedal, the switch is broke or knocked out of position. A common problem.

Next, there are small wires for the starter solenoid. You can use a test light on one removed wire and ground the test light to the vehicle, the other end in the small wire. Turn the keyswitch to start, with brake pedal pressed and see if it lights up. If it does light up, the starter solenoid may be bad.

Battery level. Ford Anti-theft and some say Battery-saver, can cause both starting and charging problems. A fully charged battery can be at 13.2V- 13.6V. When Ford systems detect low voltage it can activate the Anti-theft, battery-saver, and even disconnect the charging system to allow the battery to completely drain. In some cases the Anti-theft drops starter voltage to around 7V so the starter will not spin. Have the battery tested.

I know of 2004 trucks that were jump started and showed charging, then after 5-10 minutes they lost the charging system. Some people lost the charging system at 70MPH and drove until they stalled. All because of the automatic features built into the trucks. A new battery fixed the problem. Your problem could stem from this.

sounds like aaa might have popped your main fuse. i would call aaa back and tell them your problem. they are responsible.
