I would suspect the ignition switch in the column is the issue. NOT where you place the key but the electronic part behind the key. Hope this helps

SOURCE: Intermittent loss of engine power in 1998 olds bravada

Unhook your battery (neg terminal), let it sit for ten minutes, then start the car and let it run for two minutes without touching anything. This resets the computer, I had a Buick that required this about three times a year, fixed it every time. If this isn't your problem, is is getting progressively worse? Look at the coil, it may need to be replaced. Of course, make sure your air cleaner is clean. Do you have any codes in your computer? Go to one of the discount auto parts stores they will read it for free. Of all the sensors, it may be the mass airflow sensor, look atr this link, it is located in air delivery system connected to your air cleaner housing. If you pull it out DON'T BREAK THE WIRES IN IT, but you can sometimes clean them with denatured alcohol and a Q-tip.

SOURCE: draining cooling system 2001 olds bravada

There is a drain plug on the radiator on the divers side, inside at the bottom. Note: most of the time when the plug is removed the O-ring get's damaged and needs to be replaced since it sticks to the radiator. Most of the time it's quicker and easier to disconnect the lower radiator hose on the passenger side and let it drain there. Most of the newer radiator don't even have a drain plug and if you want a drain plug,you'll have to drill a hole where the drain plug should be and place one there. The drain plug is around $4.99 at most Auto Parts store. Good luck and hope this helps.

I have a chrysler 2003 300 m that I changed battery out in now the car will not start can anyone tell me or show how to get information on how to disable or bypass alarm system


In changing the battery, you may have wiped out the security system in the vehicle and it needs to reset. Because you have a chip in the key, it needs to communicate with the receiver. Try this but first you need to make sure the battery is fully charged or connect a charger. Insert the key and turn the key until the accessory lights come on but do not start vehicle. Leave in that position for ten minutes. After ten minutes, turn the ignition switch off and back to accessory for another ten minutes. This must be done 3 times for a total of 30 minutes. On the 4th try, start the vehicle. If this is done correctly, your vehicle should start. I hope this helps. Good luck.

I have a new battery and alltinator but my car still wont start


Have the starter tested! Check the cables to see if they are in good condition. Check the cable that goes to the starter. They all need tight connections.Don`t know the year,make and model. but older cars have a solenoid switch that is not on the starter.
