I have a 2003 f-150 while driving it died and wont restart. we tried to jump start without success. the overdrive light light came on and the antitheft light came on. now the Antitheft light flashes when trying to start.does any one have any ideas?

 

Have you tried your spare key?

 

that is the only key we have

 

Gotta go with the basics first; fuel, air, and spark

 

If the anti theft light is flashing while trying to start, you have a key problem. First step is to try another key. Unfortunately, you don't have one. You are going to have to tow it to a dealer and cut and program another key, then see what happens.

 

Thank you everyone for your help. as it turns out the problem was a bad battery. It would start after being charged. but the battery would not hold a charge and the vehicle would not start or would start and die. replaced the battery and it has done fine.
