Being a ase mechanic for 25 years, iv'e seen many a buick v6 do this. the camshaft chain upper sprocket (the bigger one) has a magnet glued on to it. This is what the camshaft sensor reads. THEY ALWAYS COME UNGLUED, usually after 60k miles or so. Replace timing chain set will fix it.

SOURCE: locating VATS module under dash

It is located above th glove box you will need to take the upper dash pad off and the glove box asbly out and the module is attached to the dash reinforcement at the top of the glove box vats modules very rarely go bad it could be the ing lock cylinder ck for contanuity of the 2 wires at the bottom of the steering column in the orange insulation with the key in the lock cylinder and ohm meter across the 2 wires you should get an ohm reading then turn the lock cylinder and if the wiring goes to open the wires are broken and the lock cylinder needs to be replaced.

SOURCE: 95 camero - having vats problem that seems

Go to this website and it explains your VATS in detail it sounds like your VATS may have been disabled but as I am not there to see the wiring harness or if wires have been cut I can't say for sure, But go to this website http://vats.likeabigdog.com/ and it goes into great detail with instructions and photos. to answer your issue.

Hope this helps please do not forget to rate/vote or place a testimonial on my advice and if I can help further please do not hesitate to ask as i have a 1984 Camaro Z28 in my yard that we are starting to rebuild and have owned several and performed my own mechanics because I wanted it safe and right. And my husband is a 22 year controls electrician in concept design and engineering so when in doubt I can ask him also.

Part of the BCM. On mine I got a new lock cylinder and put old chip key in it. Then found the wire to the old one at lower part of steering column and plugged it in . Started car with extra key I had thus by passing the removal of the old lock cylinder. Hid new cylinder with key in it under dash and secured. no more chip keys needed.

How do I remove alarm brain box from wiring on a


"I bypassed the immobilizer circuit only on my alarm module (which is really tedious). Bypassing the whole
module is possible (and little easier), but you will lose the use of the remotes and the ability to arm the alarm.
The alarm module in my '97 900 SETC is located under the carpet, below the driver's power seat switches (a
pain to get at).
If you want to bypass the module completely:
1. Disconnect the battery (make sure you know the radio code-if needed)
2. Unplug the connector from alarm module and remove module from car
3. Install a wire jumper between pin 8 and pin 20 in the connector
4. Install a wire jumper between pin 9 and pin 21 in the connector
5. Install a wire jumper between pin 10 and pin 22 in the connector
6. Wrap securely with electrical tape
If you want to bypass the immobilizer circuit only:
1. Disconnect the battery (make sure you know the radio code-if needed)
2. Unplug the connector from the alarm module
3. Cut the following wires from the back of the connector and splice together as follows (Don't cut the wires too
close to the connector, because someday down the road you may want install a new module, so you'll have to
reverse this process):
4. Cut the wires to pin 8 and pin 20 and splice together w/ wire nut
5. Cut the wires to pin 9 and pin 21 and splice together w/ wire nut
6. Cut the wires to pin 10 and pin 22 and splice together w/ wire nut
7. Secure all with electrical tape
8. Reconnect the connector to the module
Not knowing the details of your problem, please be aware that this may, or may not, solve it. Good luck and let
me know how you make out."

My 97 buick lesabre will not engage the starter when I turn ignition to the start position. The starter only has the positive cable and a purple wire going to it. I can manually apply the 12 volts to...


If the anti theft light is on,turn the key to on and wait until that light flashes or goes out,(may take 20 mins)then it has relearned the key code.Hopefully that's all it was that prevented power from completing the starting circuit,which includes the neutral safety switch in addition to the ignition switch and anti theft module.Also try putting it in neutral and try to start it.

The security light comes on then it takes 3 min to go off started doing every 2 times a month now almost every time i start it do you no what the problem is


You have resistor in your key that some people call a chip, but it is simply a resistor. The ignition switch reads the resistance and enables the starter and fuel pump if it is correct and all 1990s GM products with the VATS (vehicle anti theft system) sooner or later have trouble reading the key resistance due to wear on the key and the ignition switch.
Your solutions are relative to your abilities and finances.

1. Most expensive, take it to a dealer or mechanic and have them replace the ignition switch and keys. Cost from $250 to $400 but leaves the VATS system in original condition.

2. Aftermarket VATS bypass modules are available in the $70 to $130 range but then a mechanic will want about the same to install it. All it really is is a box containing enough resistors that you can switch it to match the combination of the 12 different resistor levels produced in the original keys.

3. Requires a small bit of ability but is relatively easy and extremely cheap. (Cost less than $5 for me to do my '97 Riviera) There are 2 small wires leading from the ignition switch that are usually inside of a small rubbery covering somewhat like heat shrink tubing. They feel different than ordinary wires and come off of the ignition switch seperately from the normal ON/OFF/Accessory/Start wires. You will need to remove the lower steering column cover to gain access. Be sure to disconnect the battery and leave the big yellow wire alone, that's the airbag! I took my key to Radio Shack and measured the resistance of the 'chip' then bought 2 resistors that added up to that amount +5% and a pair of bullnose wire connectors. I soldered them in line with each other and a connector on each end of about a 3" piece of wire and put shrink wrap around them. Then I clipped the two 'reader' wires leaving the switch dead ended and put the matching bullnose ends on the two wires going to the VATS, plugged my wire with resistors in line, zip-tied it in place and now the car thinks the proper resistance is in the 'reader'. All other functions of the VATS system are unaffected. The car starts everytime.

Certainly cheap and effective, but if you wallet outweighs your confident as a do-it-yourselfer, please refer to solutions 1 or 2.

The only other option is to continually wait that 3 minutes for the VATS reset which is not only aggravating, it continues to get worse and more often with time.

Hope this helps!

I dont know where to hook up immobileizer bypass wire


An immobilizer bypass is an electrical circuit which allows current to flow to whatever component is starved of current to keep the engine from running (usually the coil). The immobilizer opens the circuit to the coil, the immobilizer bypass closes the circuit to the coil.

If you didn't install an immobilizer circuit, then you don't need the bypass. There are probably instructions you missed in the manual explaining the immobilizer circuit.

Security system


There is a way to do this with a resistor I donot know how but you can do it with security bypass module for a remote start system. You can purchase these any where that sell remote starts. Follow the directions for installing the module but on the wire it tells you to hook to the remote start, ground it or hook to a key on ground if you can find one. Any questions please ask.

1996 LeSabre Engine will not crank over


This fix was for a 1996 Buick LeSabre.
I found the key reader in the ignition switch was faulty.
Made up a resistor pack to match the key resistance, cut the orange wire which comes out of the steering coloumn (it contains two white wires) from the reader to the VATS module and soldered it into the two white wires going into the VATS module.
This bypasses the security system so now any properly cut key will start the car.

91 Buick Park Ave won't start


i just came across this problem myself the other day. i have a 91 buick park avenue that sometimes won't start. i checked several things out like cable connections and coil pack etc. etc. come to find out it was the wiring that came off the coil pack and connects to the crank sensor. the wiring that ran over top of the water pump had finally heated up so bad the coating on the wires had melted and when the engine got hot enough the wires would come in contact and send false signals to the computer not letting it start. after the car cools down and the wires contract it would start. so check the wires from the coil pack to the crank sensor to make sure the wires are not melted together.
