I have a 1997 Buick Park Avenue that won't start. The engine is a 3.8L FI OHV 6cyl. I have replaced the Fuel pump, fuel filter, battery, terminals, the fuel pressure regulator vacuum hose and connectors, Coil pack, wires, spark plugs, fuel pump wiring harness, and radiator hoses. I have made sure all fluids are at the correct levels and pressures. My car will turn over but acts as if it is receiving no spark or fuel. The wires connecting to the part that the coil packs fasten to appear to be damaged but I am unsure. Any ideas from a fellow Buick owner?
