SOURCE: 1994 pontiac bonneville.car starts but stops after

This car uses a key with a transponder chip in it. The ignition reads the value of the chip thru 2 small contacts just inside the entrance of the keyhole. These contacts are known to get dirty, wear out, or become totally disconnected from the wire they are hooked to. Use electrical cleaner in the lock cylider and run the key in and out a few times to clean the lock. This is your temporary fix. The next item you may want to try ,is having another chip key made. If this doesn't work, then you will need to replace the ignition cylinder. You can try "Plastichead Keys" for these parts. They can be reached at plasticheadkeys@aol.com.

SOURCE: My security system in my 1992 pontiac bonneville

Sounds like your theft modulator has gone bad. The same thing happened on my 94 Deville. Try Disconnecting the positive cable from your battery for 10 minutes to reset the system. If That doesn't work look into replacing the theft modulator.

SOURCE: my car makes a humming noise when excellerating

If WD-40 got on belt, and squeak went away for a while, it may just need a new belt. The humming noise sounds like a worn wheel bearing that should be checked and replaced if needed. If squeak goes away when you push slightly on brake pedal, it may be rotor on same side as wheel bearing making the noise due to slight shifting of rotor because of worn bearing.You can try swapping tires on front from one side to other to confirm it isn't tire problem as well. If noise shifts to other side, then it's a tire.

Testimonial: "was told that it could be the wheel bearing so actually you helped push me to have it fixed. thank you."

SOURCE: how to remove radiator on 1992 pontiac bonneville

Removal & Installation

  1. Disconnect the negative battery cable.
  2. Drain the engine coolant into a suitable container.
  3. If necessary for access, remove the air cleaner, mounting stud and duct.
  4. Remove the upper fan mounting bolts.

On some vehicles, such as this 1998 model, remove the upper fan mounting bolts
  1. Unfasten the retainers, then remove the upper radiator panel.

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old. To avoid being burned, do NOT remove the thermostat housing cap while the engine is at normal operating temperature. The cooling system will release scalding fluid and steam under pressure if the cap is removed while the engine is still hot.


  1. Remove the cooling fans, as outlined later in this section.
  2. Disconnect the coolant reservoir hose from the radiator neck and the radiator hoses from the radiator.

SOURCE: replace horn fuse in fuse panel of 1992 pontiac bonneville

Your fuse box is located on the driver side under the dash board. Up above where your brake and gas pedal are located. There should be a plastic cover that can be snapped off to reveal all of your fuses and on the inside of this plastic cover there should be a diagram of the fuses that are in use.

Pump is probably stuck. Pound on tank with a rubber hammer or wood bat (no metal) with the key on. Pump should make a humming noise for 1-5 seconds after key is turned to on if working. Next replace the filter.

2004 Pontaic Bonneville humming noise wheel bearing?


I had a similar problem, when turning to the right or on a right curve, the noise would go away. After some research I found it was the left wheel bearing assembly. I replaced it and the problem is gone. Therefore, check the wheel bearing assembly. You may have to replace it.
