Question about 2003 Buick Century

2003 Buick Century occasionaly won't start

This happens once a month, or so. If you give it a few minutes, it starts up like a charm, and we have had no other problems. My husband has tried to locate the solenoid, but can't find it. Any suggestions are greatly appreciated.

    Thanks for the help. We had the battery tested, and it came back good. We are waiting for it to act up again, so we can test the neutral sagety switch. If that doesn't work, my husband is going to replace the starter. Again, thanks a lot for your help!

I just had the same problem. One possibility is that the chip (actually a resistor) in the GM VAT pass key may be going bad - or (even better) might just be dirty. When the pass key fails, the anti-theft system will lock out for 3 minutes and then will allow another attempt to start the vehicle.

Here are a couple of related links:

Good luck!

The solenoid is on the starter . I have found in most of the Buicks a weak or low battery is usualy the reason. Follow the cables, address any loose or warn ones or if the cables are corroded replace them. And a few customers have brought them in where the neutral saftey switch has gone bad. You can check this by placing the vehicle in neutral, "holding the brake" .And turn the key to start. If it starts with no troubl, that is the problem.
I do hope this helps, please let me know.

    I don't mean to sound like a complete airhead - but what do you mean "holding the brake". My car is doing the same thing - it wont start. We can bypass and jump it but it wont stay running for more than a couple of seconds.

2012 Toyota Venza.I pressed the start button and nothing happened. I made sure I had my foot on the brake and it took 2 more tries before it started.Then when it started, the time/display was reset.


If the battery is original it is likely the battery has failed. A poor connection at the battery is most likely in that it did start after a few try's, Suggest confirming the battery terminal connections are secure. Check with meter battery battery charge.
If the battery has gone completely dead it is likely the computers and some driver settings have reverted back to original manufacturing settings. Idle can be a problem if this happens, Do not be alarmed if this occurs. You may need to maintain a slight pressure for several minutes as the engine computer relearns the idle setting.

It is also possible the computer may have reverted to a limp home mode do to the electrical interruption. A reset of the computer may be required. This can be accomplished by disconnecting the battery for a few minutes to allow for the computers to reset.

Hope this Helps?

This is a devious problem which could lie anywhere. So many things not functioning would perhaps be a ground problem. Maybe take some extra care in cleaning the battery terminals, check if the ground wire is connected to the chassis. Do you have rodents in your area? Maybe they nibbled some wire somewhere?

My husband states no power in fuel pump;has no power in igniction coil;has no in starter--only does click,click. that all he has checked so far.Scanner does not give out any codes. Comments: Jun 25, 2009-...


Well it sounds like you have a relay problem. It can do that. The terminal you speak of probably has nothing to do with starter at all. a flasher or something, so unplug in and see if the signal light stop working.
Firstly check to see if there are any recalls relating to the problem you can talk to a dealership or good parts store, try silver or auto value. next get a wiring diagram and find the starting relay. Its under the hood somewhere, it changed from year to year but may be over by the battery. Then once you have found it check all electrical connections and make sure they are good and not corroded away. Then if that seems fine go and see what they are worth. If it's only a few dollars replace it. then if it's expensive take it to a shop and get it confirmed that it's the problem.
Give that a try and see what happens but it meets all the things you have said.

My daughter's 1990 Honda Civic occasionally will not start. It cranks fine, but it will not turn over. Usually, if she waits anywhere from 5-15 minutes, trying to start it every few minutes, it will crank...


if the car just wine's when starting like it would normally and nothng is happening...Check for fuel, either find the fuel pressure relief valve near the rear of the engine, and depress the valve stem (fuel should hit the roof of hood) if not then its a fuel problem, try this a couple times, but turning the key over, and listen for noise from the gas t ank to see if the pump is actuating.. if you hear the noise while just turn the keyy to acc, not start plz comment back that you hear it , but its still doesnt start....
hope this fix's-ya!
