Exclamation PLEASE HELP! Anti-theft system activated?

Hello Forum This is my first post of many I'm sure. I wish I would have found this board a long time ago. I look forward talking with you guys and thanks in advance for any advice and tips. Anyways, to the question...
Is there anyway to tell if the anti-theft system is what is causing my truck to turn over but not start. I have already replaced the fuel pump, the fuse and relay are both working yet I cannot hear the fuel pump whirring when the key is turned on. I only have 1 key (the one with the chip that I've always used) I heard that the key itself can be damaged causing it to not read but is there a way to tell for sure if this is what's going on? I'd hate to call a locksmith out and this not be the problem. I look forward to any and all advice. Thanks again.

If it's the anti-theft system then the theft light on the dash will be blinking.

It also could be your starter the same thing happened to me you should crawl under and hit it with a hammer f that works then replace that we got a new starter cause we have the anti theft problem to it burned out the starter now we pick it up cost 115 for a new programmed key the dealership is the only place that will be able to fix it.

I'm guessing I would have to get the truck to the dealer to have the key reprogrammed?? Or is there anyway it could be done without the truck being there. It is a long way from my house to the dealership, it would be an expensive tow for sure. Thanks again.

I don't see why any one would replace a starter when the motor is already turning over .
The anti theft system will just shut down the fuel . If the theft lamp on the dash is flashing you have PATS problem . A dealer is not the only solution . Most GOOD locksmiths
can get you back on the road. Just call a few local and ask if they can handle this . It is most likely much cheaper than a dealer.

I had a similar problem on my '99 but it was intermittant. It turned out to be a loose/broken wire under the steering column(i think it was orange). The wire had pulled out of the harness plug and if the steering wheel was tilted/hit and it bounced the wire the right way, the truck would fire. I repaired the wire and no problems since. its a long shot you have the same issue but worth a look.

Did you try resetting the inertia switch? It should be under the passenger side kick plate.

Thanks again for the replies. I have tried the inertia switch and the theft light blinks when the key is turned on then goes off. I finally got a new test light so I'll be able to find out where the power is going if anywhere.

Um, do you know what the difference between a successful (allows engine operation) and an unsuccessful (inhibits engine operation) PATS prove-out is supposed to look like?
