I have a 1994 Caprice Classic that will not start. For a couple months it was taking a while to start. when i would start it would turn and turn and turn until it would finally start. one morning i got into my car and it turned turned and turned and never started again. I am going to tell everybody exactly what i replaced so far, The fuel pump, fuel filter, fuel pressure regulator, ignition coil, ignition control module, distributor cap and rotor along with having the timing chain changed, spark plugs and wires computer chip and knock sensors. Any more idea why it will not start?
