1996 Chevy Cavalier fuel system

The one person responding to your question said to check fuel pressure and he is right, but don't forget that a vehicle can have all the pressure in the world but if it don't have enough volume then the vehicle will never run right. Have you checked your ignition system? Many problems seem like they are fuel problems when in fact many times there is something wrong with the ignition system. Have you checked your spark. A spark should jump at least a quarter of an inch on a spark tester, if not the spark is weak. I know at Auto Zone they have adjustable spark tester where you can make the gap shorter or longer to see if the spark is strong enough. A weak spark could make it seem as if it is getting to much fuel because it isn't burning the fuel all the way causing your cylinder's to be flooded, hence the fact that you can't start it after running it for ten minutes. Try taking the fuel pump fuse or relay or the injector fuse out and then crank it to burn excess fuel out of the cylinders. After you do this stick the fuse or relay back in and then try to start it. If it starts look for problems possibly in the ignition system. God bless and maybe this will help if you haven't figured it out yet. Don't car problems suck, but it is a way to learn and get better!
