1998 Pontiac Bonneville - Page 2 Questions & Answers
What would cause fuel pump in a 1998 Bonneville not to run when key is in on position?
The pump is only suppose to work for a few seconds with key on/engine off. This primes the fuel system. then it runs when cranking and as engine runs. With key on it should, however, build up pressure and then shut off. Only real way to tell what is going on is use of a test guage often available at parts store loan-a-tool items. Shop manual will tell you correct pressure at key on and when running. Wrong pressure (low) can be bad pump, filter, regulator, relay or leaky injectors and other leaks. Very common for pump in tank to fail and often it will draw excess curent first damaging the relay.
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.

How do I reset the passlock code for a 98
not sure if this is what you mean but I have 2 ways.... Make sure the key fob you purchase looks like the one you originally had, and is a GM key fob. Once you have it, open the fob, pop out the rubber insert, pull out the chip, and carefully slide the battery completely out. (If the batteries dead replace it now) Now reassemble the same way you just took it apart, walk out to your car, and hold both the lock and un-lock at the same time for 'bout 7 seconds. Your car should now be accessable with the key... That will only work if the remote was already "married" to the car using the GM ODBD2 scan tool or (for your car).... OR the following procedure:
1996-1998 Bonneville
ALL TRANSMITTERS MUST BE PRESENT WHEN PROGRAMMING NEW REMOTES!
1) Turn OFF ignition switch
2) Use a 3 amp fused jumper wire and connecte the terminal 8 (blk/wt) and terminal 4 (blk) wires at the data link connector. The data link connector is located on the drivers side bottom of dash panel
3) Close all the doors
4) Turn ON the ignition switch. The locks will cycle to LOCK
5) Press and hold LOCK and UNLOCK on one of the transmitters for 30 seconds.
6) After a 30 second delay the doors will LOCK and UNLOCK.
DO NOT TURN OFF THE IGNITION!
7) Repeat step 5 for each additional transmitter
8) Disconnect jumper wire from data link connector. Then turn ignition off and verify functions.
eBay is a good source for a replacement transmitter, but understand that they are NOT interchangeable. You must use the ONE that is meant for your car.
Security light want go off so car can start 98
Check the key and make sure its is the correct one, pass lock is a pain, and sometimes the reader\transponder can go south. I would bypass it and go around the problem this can be done with a resistor.
Squealing
My first impression would be the serpentine belt is worn ...specifically it has "glazed" and stretched so it no longer has the ability to effectively grip the drive pulleys it spins. Typically when the serpentine belt loses "traction" it will squeal as it slips on the metal pulleys of the accessories it is designed to operate. There also may be a problem with the the tensioner ...a device used to keep proper tension on the serpentine belt. This is an easy and relatively inexpensive repair ...probably cost between $100 and $200 ...depending on whether the tensioner needs replacing.
You really need to get this fixed. If the serpentine belt fails ...it breaks or comes apart ...you will lose power steering and the water pump as the two critical accessories the belt operates. Obviously the loss of power steering can make the car difficult to drive and the loss of the water pump will cause an engine overheat condition fairly quickly. The A/C and alternator will also drop off line but these aren't as critical as the steering and water pump.
Why are only two of my brakes working on my 98 bonneville pontiac?
This is a litlle strange as the master cylinder has the brakes usually set up with the fronts together and the rears together. you can see if the caliper on the front is siezed and the master cylinder frozen on the rear wheel. Does the car have ABS and if so have the lights come on
Where is bank 1 sensor 1 located on a 1998 Pontiac Bonneville 3.8 ?
If you have never replaced your O2 sensors it is well past time. The normal service life for O2 sensors is generally 60-75K. Your vehicle probably has a good 200K which means you should replace all of the oxygen sensors. These sensors are a major input to the engine management computer ...specifically providing info about fuel mixture. When the O2 sensors fail they provide bogus information; replace them all and you'll find your Bonny will run a *whole* lot better.
