My 02 Bonneville is having problems starting. When I turn the key nothing turns over... the radio comes on but nothing else will happen. At first if I waited 10-15 minutes it would start right up now it seems to take longer like up to an hour. I just had the ignition switch replaced thinking that was the problem but as soon as I had gotten home with it and tried to leave the same thing happened:(

When you turn the ignition switch to start ,it sends 12 volt input to the PCM - engine computer . The PCM will then energize the start relay in the under hood fuse / relay distribution box.
Here is factory service info.
Circuit Description
Moving the ignition switch to the START position sends a 12 V signal to the PCM Ignition Crank Sense. The PCM verifies that the transmission is in the PARK or NEUTRAL position. The PCM then grounds the control circuit of the START relay. When the START relay is energized it allows battery positive voltage to the starter solenoid S terminal.

Try moving the gear selector to the neutral postion when it fails to start . To eliminate or confirm the park neutral safety switch as the problem . Are any lights lit on the insturment cluster ? Check engine , security ?

SOURCE: key wont comeout of the ignition switch, do i need a new switch?

First, spray a bunch of WD-40 into the key cylinder -- use the red tube which comes with the can to do this -- put something on the floor to catch the oil dripping down.

This has a good chance of solving your problem. After a couple of days, buy some graphite lubricant (Pep Boys) to blow into the key cylinder. Repeat the graphite every month or so for 6 months.

SOURCE: 96 pontiac sunfire wont start.....

Starter solenoid , or wire that leads to it.

Also , if standard transmission , may be the switch on clutch pedal is intermitant.

Engine won't turn over unless it thinks you have your foot on the clutch.

On many cars, if the battery is dead, it locks the key in the ignition. Put a battery charger on the car or replace the battery and give it a shot.

Good luck.

98 pontiac bonneville-ignition not engaging

There are a few components that could cause the problem. Bearing in mind the hard turn issue last week, I would first suspect the manual ignition switch, which is located on top of the steering column under the dash( not the key switch). All other components would not affect the hard turning issue, other than a dry ignition lock cylinder, so that's why I would first check out that mechanical switch.
I don't know your level of aptitude or what tools you have, but this is not a very difficult fix - but it will take time.
If you would like to fix this yourself, let me know and I will be happy to help walk you through the procedure.
Hope this helps!!

Car won't start

If you cannot hear the starter motor, check fuses, there can be a broken contact to motor or ignition barrel faulty.

Turn key wouldnt start

Possible causes, flat battery, faulty alternator, coil or starter motor,though sounds more like power problem, do you have power to lights, radio etc when key is turned on even though nothing happens.

1995 Bonneville

the problem is probably one of the battery cables. check for looseness and corrosion. especially at the positive battery connection where the two cables are stacked.
