Security fuse 1999 pontiac bonneville

Need a little more info . Security fuse ????? Do you mean anti-theft ? The SECURITY light is lit on the instrument cluster ? Content theft or vehicle theft ?
Vehicle Theft Deterrent (VTD) Description
Ignition Key
The ignition key for vehicles which are equipped with the PASS-Key® II system consists of the following components:
• A typical square ignition key blank
• A resistor pellet
The PASS-Key® II ignition key has the same mechanical key cuts as a non-PASS-Key® II ignition key. You can not service the key blank and resistor pellet separately. There are 15 different ignition key assemblies, each with a different key pellet resistance value.
When you service the PASS-Key® II system, obtain all ignition keys. Verify the proper key code values withJ 35628-A Interrogator.
Steering Column (Ignition) Lock Cylinder
The steering column (ignition) lock cylinder that is used with the PASS-Key® II system contains a set of electrical terminals. The terminals are used to contact the resistor in the ignition key.
The wire routing for the contacts inside the steering column is very critical. When you service the lock cylinder, maintain proper wire routing.
When you replace a steering column lock cylinder, make new keys. The new keys must match the following items:
• The PASS-Key® II code of the PASS-Key® II system
• The mechanical cut of the new steering column (ignition) lock cylinder.

Measure the resistance of the pellet on the key , go to radio shack an buy a resistor of same value an solder into wiring harness .

pulling fuse won't work , power's the PCM as well . Plus software in the PCM won't let it start if it doesn't see input signal from the Theft deterrent module .Take an get it fix right .

How do I reset security system on my 2000 Bonneville?

press the helpful button and follow me on fixya for more tips

Put the key into ignition and turn it to RUN position. All dash lights will illuminate. Don't try to start the car. Leave the key in the ignition for about 5-10 minutes or until security light will stop flashing. The car should start after that. Security lock on the Pontiac disables the injectors, so the engine should crank. If it does not, you may want to check ignition switch, fuse and relay for the starter. Try to reset security first. Sometimes the magnet in the ignition lock cylinder gets dirty and needs cleaning. written by AlexGS
If the above procedure does not work the first time, try again, but right at the start insert key in and out of ignition several times to get good contact, as your key or ignition could be faulty.

Security light let want let my 98 bonneville start

The security light picture/icon is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle.

Security Module location

Does the SECURITY light on the instrument cluster flash or is it on steady ? The problem with this system is the contacts inside the key lock cylinder wear causing this problem ! It's not the module more then likely ! This system you can do a by-pass on ! Measure the resistance of the pellet on the key , go to radio shack buy resistors to = the key pellet resistance . Find the wires from the ignition lock cylinder under the dash , disconnect the connector from the dash wiring harness an solder the resistors into the dash wiring , not to the lock cylinder . There are videos on youtube showing how to do this by-pass .
When a key is inserted in the ignition, contacts that are located in the steering column (ignition) lock cylinder contact a resistor pellet located in the ignition key. The theft deterrent module measures the resistance of the key pellet. The module compares this value to a value stored in memory. The theft deterrent module then performs one of the following functions:
• If the values match, the theft deterrent module performs the following system enable functions:
• The module provides a ground for the theft deterrent relay at terminal A4 (CKT 625, YEL/BLK). The ground enables the starter to operate.
• The module sends a proper pulse width modulated (PWM) signal to the PCM. The signal travels via CKT 229 (DK BLU), terminal A3. When the PCM receives this input, it enables the fuel delivery system.
• If the values do not match, the theft deterrent module performs the following system disable functions for approximately three minutes:
• No ground is provided to the theft deterrent relay. The starter is disabled.
• No command is given to the PCM in order to enable the fuel delivery system.

How do I prime the oil pump on a 1985 Pontiac Bonneville?

It is quite possible. Most cars will have a low oil level/pressure safety switch that will not allow the car to start. As far as rebuilding the pump, the necessity only depends on your budget. It may be cheaper to rebuild it, or buy a rebuilt unit. If you do choose to rebuild it, I would definitely invest in a Haynes, or Chilton's book for your car.
