1997 pontiac bonneville will not turn over no lights or dash lights. battery is good. no radio. driving down the road, tapped brakes radio shut off. drivend down the road tapped brakes, car shut off. switched bright lights to dim and the entire car shut off. whats the deal?

You have a list of things to look for. If the battery is new, it should turn over the engine, if it is dead, why did it die? Is the alternator charging? Is the battery any good? Did you check the electrolytes? Just because it is new doesn't mean it is good. Then check the terminals, are they clean? A car will not on a dead battery, it will not with battery power only for very long. When you get done with the electrical stuff, move on to the fuel stuff. Is it fuel injected or throttle body? Either way, I would try some fuel additive to clean it up in there. If you get it running. Some of your sensors could be bad. Sometimes the carbon builds up in there and throws the car into a fit, it won't run good at all. Are the dash board lights going crazy? A sign of the alternator going bad.

Either dead battery or bad fusible link. Charge the battery and if the lights do not come back, then check the fusible links (usually near the starter).

It is none of the speed sensors.The 1214 is system contact or coil open.The 1248 is for the ebcm turned light on.These 2 are for the electronic brake control module.The 1245 is for the low tire pressure.And the 1287 is for the steering wheel position sensor.What you should do first is clear the codes and road test the vehicle.When the light comes back on check and see what codes came back.The electronic brake control module is for the antilock brakes and the traction control.When you get the codes after driving the vehicle post back with them and I can help you with whatever codes you have.Good luck.

are your dasboard lights at full brightness?Turn your headlight switch(it may be on the interior light detent).BTW I drive a '97 Bonneville SE and one great thing about these cars is that if you leave a light on it will shut off after about 5 minutes so it won't drain your battery overnight.

A bad ground from the battery. Clean battery cables and replace bolts, check alternator for output.

I would take a look at the throttle position sensor being faulty, but I can't explain why there is the only one fault code. Hope this helps. Good luck.

U have most likely damaged a wheel sensor ring, in order to ID the one you damaged u will need to have the ABS/TRACTION CONTROL system tested for trouble codes, this will lead to the right area for repair.

I am having the same problem and also occasionally the cruise just shuts off when I am driving on dry, straight roads. Code C1288 was cleared, but it continues to happen. I was told that the electric brake module needs to be reprogrammed and that it will cost about $80.00. They are still looking into it.

do you have any thing extra hooked up to your battery because i have a 96 and my amp kills the car when im sitting still abs light cuts on then i lose power for a few seconds

Try checking the starter solenoid wires.Make sure the wire hasnt come loose and the battery to solenoid cable is tight.
