I have a 2000 f-150 4.2L 5speed this moring i got in my truck to start it and nothing it wouldnt turn over ive checked all the wiring/battery i have also changed out the nuetral saftey switch and the ignition switch and still nothing the only other thing that i could find that might be causing it not to start is the anti theft system i was wondering if anyone new of a way to disable this to see if it might start? if anyone could help asap that would be great!

spray some carb cleaner into the air filter housing and turn it over, if it makes an attempt, it is probably the PATS (passive anti-theft system) Is the light flashing very fast in the cluster? If so it will be the PATS for sure. Do you have another key? try the other key. If the other key doesn't work it will be the transceiver for the PATS.

There is no way to bypass the PATS system. Once it is enabled, it shuts the fuel system down.

Do you have a remote start in the truck?

no i do not have an extra key and no there is no remote starter on it ... so what do i have to do if the PAT is activated??

Hit-By-Thunder

check the connections to the transceiver for the PATS. this is located in the upper and lower steering column plastic covers (upper and lower pieces) You will see a black ring around the ignition tumblers. this is the antenna for the tranceiver. Follow the wires to the connector to see if the connector is infact plugged in wiggle test it to be sure. If this does not work do the carb cleaner trick to verify that the fuel system is disabled, PATS will shut the fuel pumpsystem down once triggered. If it does fire with the carb cleaner, it is the PATS. The truck has to go to the dealer to be reprogrammed. Sorry for the bad news. If you had another key the dealer will be able to reprogram from that key. Keys usually don't go bad it is usually the tranceiver.

If the theft light is flashing rapidly you have a problem with the PATS. If its the normal random flash, its ok.
