car is not starting sometimes

Asked by Apr 06, 2014 at 11:07 PM about the 2008 Buick Lucerne CXS

Question type: Maintenance & Repair

The first time car wouldn't start, I replaced the fuel pump. It did it again a day later,I  then put HEET in gas tank and it started up. No more problems until about a month later. It wouldn't start so put Lucas in, it started. Went back an hour or two later and will not start. What could possibly be the problem?

This garbage they call fuel today will pull moisture right out of the air, what you are describing is a lot of water in your fuel tank, if you can try to take a sample of fuel right out of the fuel filter and let it stand for a while, you should be able to see the fuel and water separate in the bottle, unfortunately if you have a lot of water in the tank you need to get it all out, and that requires dropping the fuel tank. After that is done put in a bottle of Techron with a fill up and then put in a bottle every other tank, that should keep the water at a minimum, and watch out for cut rate fuels as they contain more water than a good grade.
