Is your "THEFT" light blinking at all in the dash? Or does it come on when you turn the key on, then shut off in a few seconds? You could have an anti-theft system issue.

it blinks before i turn the key and then once i turn the key, it stop blinking but the light stays on.when i turn the key i get nothing but the dash lights up.i had a 2000 explorer and when it didnt recognized the key,it would spend over but wouldnt start.

If it blinks before turning the key, it's a PATS system issue (the anti theft key / transceiver / etc)... Try a different key first...perhaps another known good one. The 2000 and 2004 Explorer have different architecture for the PATS system. In 2000 the starter would engage, and in 2004 it does not.

thanks for all your help. i was beginning to think the problem was the ignition switch. do you know what the symptons for the bad ignition switch or do you believe that the problem really is the key and needs to be reprogrammed? thanks again.

Simply put: Put the key in, turn to the on position, do not attempt to crank. In the on position, if the THEFT light flashes, the key is not communicating. Don't look anywhere else. Good luck!

Have you made sure your shifter is fully in park or neutral? Try neutral if you haven't... It doesn't even click when you crank it, right?

i have tried both park and neutral. no it dosent click

I would even go as far as to check the wiring and operation of the transmission range sensor. Really, it's tough to do more than you already have without some diagnostic equipment. With diag equipment, you can security access and reprogram the key. You can monitor the TR sensor position. You can check for various component function. I'm sorry to say that you may have to get to that point...

Probably the best idea. Hey, sorry we couldn't make it happen! Definitely fill me in on the findings. Good luck!

the ford dealer dida diagnostics on the truck. they had to reprogram the computer in the truck as well as the keys to get it cranked. said they weren't exactly sure about what caused the computer to lose the info, but it did the trick. cost about $120 to fix in case anyone else runs into the same problem. thanks again for all your help
