Question about 1991 Buick Park Avenue
When you turn the key on you should hear the whine of the fuel pump building pressure up in the fuel line. Turn the key to the on position(but don't turn over the starter), turn it off and then repeat two or three times. Get out and see if you have any fuel pressure in the line. If not your fuel pump is either shot or your fuel pressure regulator needs replacing. Have you removed a spark plug to see what it looks like? If it's a light tannish, grey color then it is obviously a fuel problem and I would check as I said above. If its wet and dark colored then it is a spark problem.......or it could be the fuel pressure regulator is letting fuel by as the pump runs so it dumps in the cylinder. If that is the case you will have oil level higher then full and it will smell like gasoline.
