    Could be a few things. I would start with checking the ingnition parts (distributor cap, rotor, plug wires, spark plugs). Then check the PCV, hose to the TBI injector Body. Check the body for Vaccume Pull. High Milage TBI units are known for buildup inside that blocks or restricts vaccume. Charles

    If it ran great the night before you must have replaced the ignition parts correctly. When you say "won't" start, what is it doing? Charles
