Where is the starter located on my 2002 buick rendezvous?

It means the engine computer lost the theft pass code from your ignition key. This could be caused by a bad chip in the key, or a problem with the ignition tumbler or steering column wiring (many times older high mileage vehicles the wiring breaks in the steering column causing the signal to be lost intermittently). If this happens while your Buick is running, it is warning you it MAY not restart if you turn it off because a loss of theft deterrent code was detected. If this happened when the key is turned on, but engine not started, the engine will not start as the engine computer thinks the car is being stolen.

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem.

Does it crank but won't start or is it a crank no start? Does the starter solenoid click or no click is heard? You need to state in detail what sort of testing has been done and the results along with detailed symptoms in order to help you better.

id say starter or alternator is bad i would think thats why its clicking

We just went through this with our 2003 Rendevous. Clicking like crazy but wouldn't start. Replaced the starter but still doing the same thing. Our next step was going to be replace the battery (which tested well) and the ignition assembly. Out of frustration, I hit the top of the hood and the headlights came on!! Further investigaton proved that the problem was a corroded ground wire on the battery. Hope this helps

may be netual saftey switch.turn key to crank/start and hold it.same time wiggle shifter be rough if starts its netural switch

If it starts by jumping the starter you have a faulty electrical ignition switch

If you hear a click sound near the motor and your battery is good, you may want to have your starter checked out.

oh thats the change oil light expect it every 3500 to 4500 miles they glow.. you can usually reset it by holding down the trip button with the car off and then turn the key to the II position where everything lights up

The first thing I would do is be sure that your ignition switch is not shorting out, then I would be looking at the solenoid on the starter. The solenoid is the most common thing that fails and causes this to happen, eventually it will burn out and the starter will be done for. The reason I suggested checking your ignition switch first is because of the simple fact that I don't know your cars history. Good luck and remember to rate all the solutions that you get on FixYa, thanx
