SOURCE: How do you nturn off loose gas cap alert?

You need a scanner to do that, but...after so many starts of the engine, if the problem is solved, the light will go away. (I seem to think it's 50 starts)

A factory fuel cap would be a good start. The other possibility is that the vent solenoid is stuck open. Ou can buy an inexpensive code reader for about $50 that will both read and clear codes. If the new dealer gas cap took car of the problem than the light will stay off after you clear it. If it was to the problem than the light will come back on. The EVAP system can be checked with a smoker. Any good shop that deals with these problems will have one. Let me know if you have any questions and I'll do my best to answer them.

Problems opening the gas cap for removal when gassing up my 2004 Buick Rendezvous. Just bought a new cap and same problem, won't open


If the cap is hard to remove, this is a common problem with older GMs. The mating surface at the end of the filler tube becomes slightly corroded and is sticking to the rubber seal on the cap. Plug the filler tube with a rag (to avoid any explosive hazard), clean the mating surface with lacquer thinner, gently buff it with crocus cloth and try that. If it still sticks, lubricate the cap rubber seal with a thin coat of a lubricant (ONLY one approved for rubber/plastic materials).

2000 Buick Lesabre has security light, check engine & gas cap loose light on?


I'm sorry you feel that way about mechanics but there are those that you can trust. I'm a diesel mechanic and have been in business in Australia for 20 years and I am disappointed to hear this sort of statement.However it is possible that what you heard is true??The high-performance engines today rely on the fact that they are a closed system. That means that any leaks in the system be they air or water or gas.
I know that many engines will stop if you remove or loosen the filler cap for the oil. Likewise if they lose pressure in the fuel tank they will have performance problems.
I would enquire around your neighbourhood for the name of a really good trustworthy mechanic and you will find or should find a good and trustworthy mechanic and ask his opinion.
With regards

Error code P0440 on a Buick Park Avenue, year 2000


It's an Evaporative Emission Control Malfunction. Sometimes as simple as a new gas cap. If you recently put gas in your car and left it running while doing it, this would give you that code

2000 LeSabre starts but runs very rough and stalls. After


Sounds like the plugs are not firing hot enough on initial start-up. Try a quick spark plug change, and clean throttle body. The gas being injected, isn't being burned fast enough by the plugs, which causes the car to have a hard start-up. You may try a higher octane gas or Lucas injector cleaner with your usual octane rating. Lucas comes in a very small bottle, and works very well in my opinion.

Need to remove the fuel pump


Remove the bottom of the rear seat, underneath there is a cover wit 4 or 6 bolts, remove the cover and you gain access to the top of the gas tank, remove the cap and there you have the fuel pump, if this model dont meet this criteria you have to remove the gas tank.

Vaccum line problem


Have you had a diagnostic scan ran? It sounds like you may be having a problem with the MAF sensor. The MAF regulates the amount of air taken into the car. The sensor responds to the engine temperature.
