Why does my ignition module keep going out on my 2005 Bonneville?

Frequent ignition module failure can be caused from an over-voltage condition from the voltage regulator. Check your charging voltage at the battery when the vehicle is running, and it should not be higher than 14.3VDC.

Also, improper jump-starting using a "booster" style jump-starter can cause an ignition module to fail. Did the failure occur after jump-starting? Try using a standard trickle-charger in the future instead of jump-starting your car from a booster, or simply use jumper cables attached to another vehicle or fully-charged battery.

Be sure that the voltage at the primary side of your ignition coil is no more than 6.5VDC. If it is, replace the ignition resistor.

Are you sure the battery isn't low, possibly a charging system problem, have that checked first then if that isn't it let me know.

could be faulty gauge or sending unit in the tank. if you can get ahold of a scan tool, see if the fuel lvel reading on the scan tool agrees with the gauge. if it does than you have a faulty sending unit.if it does not than you may have a faulty gauge.

My security system in my 1992 pontiac bonneville is blinking and my car wont start what can i do, i have a reset key where do i put it

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.

1997 Pontiac Bonneville runs fine for hours, but then charge dies

Make sure the battery is good and fully charged . You will get the code if the battery is bad on the transmission.Check the ground wire from the engine to the frame of car. Must have a good one. Check to see if the battery cable is getting hot. The gauge inside the car could also be bad. A few things you should look at

Fuel gauge not working all the time.

This is a normal concern.
The instrument cluster uses 4 different operating modes to calculate the fuel level:
Anti-slosh (default mode)
Key OFF fueling
Key ON fueling
After a fuel fill up, the time for the fuel gauge to move from empty (E) to full (F) ranges from 2 seconds to 55 minutes depending on which operating mode the fuel gauge is in.
The default fuel gauge mode is called the anti-slosh mode. To prevent fuel gauge changes from fuel slosh (gauge instability due to changes in fuel sender readings caused by fuel moving around in the tank), the fuel gauge takes approximately 55 minutes to go from empty (E) to full (F).
The key OFF fueling mode (2 seconds to read empty [E] to full [F]) requires 3 conditions be met:
The key must be in the OFF position throughout the entire refueling of the vehicle.
At least 15% of the vehicle's fuel capacity must be added to the fuel tank.
The instrument cluster must receive a valid key ON fuel sender reading within 1 second of the key being put into the RUN position. The key ON sample readings are considered valid if the fuel sender reading is between 15 ohms ± 2 ohms and 160 ohms ± 4 ohms.
If these conditions are not met, the fuel gauge stays in the anti-slosh mode, which results in a slow to read full (F) event.
The key ON fueling mode (approximately 90 seconds to read empty [E] to full [F]) requires 3 conditions be met:
The transmission is in PARK (P).
The key is in the RUN position.
At least 15% of the vehicle's fuel capacity must be added to the fuel tank.
In key ON fueling mode, a 30-second timer activates after the transmission is put into the PARK (P) position (automatic transmissions). When the 30-second time has elapsed and at least 15% of the vehicle's fuel capacity has been added, the fuel gauge response time is 90 seconds to read from empty (E) to full (F). When the transmission is shifted out of PARK (P), the fuel gauge strategy reverts to the anti-slosh mode. The key on refueling mode prevents slow to read full events from happening if the customer refuels the vehicle with the key in the RUN position.
Recovery mode is incorporated into the instrument cluster strategy to recover from a missing fuel level input during a refueling event. Missing fuel level inputs result from intermittent opens in the fuel sender or its circuits. Recovery mode (empty [E] to full [F] approximately 20 minutes) is initiated when the following 2 conditions are met:
The instrument cluster is in the anti-slosh (default) mode.
The actual fuel level in the tank is greater than what is being displayed by the fuel gauge
