Hello, I have a 1998 Crown Victoria. I just got it 2 weeks ago, everything was fine untill I went to start it and nothing, not even a click. When I turn the key to on the lights, dash and radio work fine untill I turn the key to start and it all goes dead, not even a click. So far I tried to jump start it, replace batts. I even tried jumping the solenoid if thats what its called. Any ideas? Thanks
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily for more than three seconds when the ignition switch is turned to RUN or START. PATS also flashes the theft indicator lamp every two seconds at ignition OFF to act as a visual theft deterrent.
I couldn't find any place that showed starter being disabled with PATS. I know the newer ones won't crank but I don't remember tha older ones. Here's the diagram for the system. Have you tried putting it in neutral and trying?
When I turn keys the security lights stay on constant for 3 secs then goes blank. I tried starting the car while in neutral and still nothing. Someone told me to jump start solenoid, I tried and it sparks and turns but engine wont start. Is there a second solenoid other that the one bolted to the starter? Thanks
You probably have a pats issue. If I remember correctly, the pats system disables both the starter and the vehicles ignition if it doesn't recognize the key that is trying to start it. The Key has a chip in it (thus the over-sized plastic part) that sends a unique radio frequency identification code, which is read by a receiver in the ignition switch, this is why hardware store key copies won't work with your car.
If the key was ever dropped hard enough or submerged in water, it is possible that it has lost its RFID code and is no longer being recognized by your car, but there could also be an issue with the pats system in the car.
The fact that the security light stays lit for three seconds is a clue, but I don't know what it means, maybe someone who dose will chime in.
the reason that jumping the starter solenoid makes the starter turn but won't start the car is because you are directly powering the starter, but the pats system is still disabling the ignition.
Whatever the problem is, if its pats related you are probably going to need to take it to a dealership, sorry to say.
If you end up needing to take the car to the dealership, you may want to consider having them program a second key for you. Once you have two keys, you can program more yourself in the car.
