Tip & How-To about Buick LeSabre

My car won't start.....won't turn over.....

When your car will not start, and is not turning over, the solution is usually pretty simple. In this tip, I will help you diagnose the three most common reason why a car fails to attempt to start. This is, by all means, not a definitive guide, just a starting point.

If your car is not starting, but the motor is turning over, this will not apply to you. Please use FixYa's search bar above to reattempt your search.

The three most typical reasons a vehicle fails to turn over are; the battery, the starter; and the alternator. Testing them are pretty easy, and even the novice or beginner mechanic can diagnose these issues and avoid a costly trip to the shop.

To test the battery, simply turn on the headlights. Are they bright? If so the battery is working well, and you likely have a starter issue. If the lights are dim or not lighting up the battery may be weak or dead. This however does not automatically declare it as the problem.

Let's do another test.

Jump start the vehicle. Pull another car nose to nose with the disabled one. With both cars turned off, hook up the cables. NOTE** always remember when hooking up jumper cables red and/or a (+) symbol are positive, and black and/or a (-) symbol are negative. Now start the running car. You should notice the headlights on the disabled vehicle are now bright. This is a sign of a good connection. If they are still dim, wiggle the connections on the jumper cables until the are bright.

Now try to start your car.

If your car now starts, you can rule out the starter as a problem. However If it doesn't start, or it just clicks, the starter is likely the cause of your problem. You can try to bang on it a little with a hammer to attempt to loosen up the frozen solenoid, which is a common problem with starter failure.

If your car did start after the jump, and you have ruled out the starter as a problem, you can now do yet another simple test to narrow it down between the battery and alternator.

OK, you jumped your car the motor is running, the headlights are on, and the two vehicles are connected by the jumper cables. Leave the disabled car in question on, and disconnect the jumper cables. Without the cables on, it is now up to the alternator to keep the motor rolling. If the car continues to run without the cables on, the alternator is doing its job, and its your battery that is failing to work as it is supposed to. If the car dies within a few minutes of removing the cables, then the alternator is failing to do it's job and need to be replaced.

That's it, in a few short minutes, you can diagnose these issue and save a ton of cash. As always FixYa's support and forums are here to help answer any other questions that may arrise. Best of Luck!!

I changed spark plugs and wires..but car wont start..what do i do??

Your year--make--model didn't post for some reason? That info would be helpful.
If no spark, check primary voltage to the coil. Are you missing anything else, fuel pressure--injector pulse? Engine cranking, do you have rpm signal?

2003 Honda Accord EX interior fan not working. Was in a downpour and had lights, wipers, radio, etc turned on and when tried to turn defrost on the fan failed to come on. Have checked every fuse/relay

the fan motor could have went out, you can pick one up at the local parts house for less than 50 bucks. its pretty simple to change on most vehicles its usually located under the hood usually on the passengers side, only about three or four screws hold it in. Most of the time they can point it out for you at the parts house. Once its located unplug the wires going to it, turn the air condition on with the key on and check the wires using a volt meter to make sure you are getting at least 12 volts to it. If it is getting 12 volts then buy the fan, if you are getting no volts or something less than 11 volts then have a mechanic check your wiring harness, as there may be a short or a wire making contact in the wrong place. Good luck.

car wont start how can i tell if its the starter without changing the part out right away

Hi there,

If it is turning over and not starting, it's likely to be something else.

If it's just clicking, that usually is a low battery.

If you describe in detail what is happening, I can help you nail he problem. It should be pretty easy to diagnose.

Best regards,

the engine light

3000 rpm? This is pretty high for idle. You need to have the stored code read from the ECM. Usually this is a simple O2 sensor but with it racing to 3000 rpm I would have this diagnosed by a tech at a shop.

door lock on 2005 -3500 truck

Yes Admin,
This is what I found out. The problem was with the power lock portion of the part (siezed). It is also sealed and unserviceable. The good news is that the part was in stock at the dealer for around 65.00. Actually pretty amazing considering how many parts there are to the device. After disassembling the door three times (once to diagnose, once to take apart and disable the power lock function, and one last time to swap out mechanism) I became fairly quick at it. If you have this problem, just go buy the part and don't mess around. Oh yeah-you'll need a torx bit to get started.....
