I'm having problems starting my 1996 Buick Park Avenue 3.8L (not the Ultra model). I know its not the fuel pump, battery, the connections to my battery from the alternator, or the alternator itself. I bought a new starter from Auto Zone about 8-9 months ago so I don't know for sure if its that or the cylinoid. Does anyone know what it might be and how I can check if something has gone bad or not??
