I had a new steering column put in the car about 2 months ago, I tried driving it, but it would die and wouldn't start up again. We changed the fuel pressure regulator and then tried starting it again and it wouldn't start. The battery was dead so we jumped it and it wouldn't crank over it threw a code 46. Which I found out that it was the anti-theft system. I tried the keys from the other car and they wouldn't turn the ignition over. What could be the problem? I looked my service manual for my car, but really didn't get any where. Can someone help?

Well I got the car running after changing the battery. But the will run for a little bit and then shut off. I would restart it and it will start, but when I give it gas it run real ragged and then die. It's getting fuel pressure through the lines and the fuel pump. I need hep, anyone that can help please help, I would greatly appreciate it.
Thanks,
Tracy

My husband came home around 5:30p.m. and he started the car and it ran ragged so he opened up the hatch and had me to turn the ignition on but not start it and the fuel wouldn't kick on so we think that it is the fuel pump. THE CAR WILL START NOW, NO P[ROBLEMS WITH THE PASS-KEY ANY MORE. I believe that it is the fuel pump any suggestions? Thanks

Sounds like the anti-theft ignition cylinder or wires are bad on the new column---they had a problem with the tiny little wires coming out of the ignition cylinder inside the column breaking from turning the ignition on and off. Probably have to have a dealer or qualified locksmith replace the ignition cylinder as long as the rest of the wiring is ok.

These cars have a factory anti-theft thing in them which is easily seen by the resistor pellet in your original keys for starting which was called VATS 1 or possibly 2. These resistor pellets have about twenty different codes or resistances to account for thousands of these out there. You not only have to get the proper key code to turn the cylinder to enable the mechanical part of the ignition switch, but the resistor in the key has to drop the voltage in the sense line to the VATS module to let the system know it is the right key. So what do you do? You take the original key with the pellet to a dealer and they will read the key's pellet for a code. Then supply them with the key that turns the new column's switch as they will have to cut a new key with the proper key code pellet in it to the new columns key design. Make sense?

46. PASS-Key II circuit
Q: How does the PASS-Key II system work?
A: PASS-Key II works with a small resistor chip embedded in your ignition key. This chips gives a certain resistance. When the ignition key is inserted into the car for the very first time at the factory the computer controller memorizes the exact resistance of that chip and will not start again w/o it.
This provides pretty good protection against all but the more sophisticated thief. A knowledgable thief can get around it with the right equipment, but the time to steal goes up considerably.
Good luck!

Apparently, the column must be integrated to your theft system. Contact the dealer service department to be sure.
