Having problems with your 2002 Mercury Sable ?
This has been an intermitent problem for some time. It has been to the dealer a few times and the last time I was told that it was the fuel pump because of low pressure? Now it will not startat all. Could it be the ignition module or something as easy as a bad crank sensor?
All of these things are possibities. You will have to run a few tests. Check your fuel pressure but not only the pressure you have to check the volume. sometimes you can have proper fuel pressure but still not enough volume. obviously if you have not fuel pressure this is your problem. also check for spark at the spark plugs then check for pulse to your fuel injectors. the ignition module can cause you to have no injector pulse and no spark. your crankshaft sensor can cause no spark also. you also have a camshaft sensor that can cause no spark. also scan the computer for any trouble codes.
