1. Are you getting fuel --inertial switch can kill the fuel
2. Had a similar problem in an F150 --turned out to be a bad power
connectionto the PCM relay. If the computer gets no power, it will kill the spark. This was odd--has a spark when the jumper is opened to set base timing. The dead computer killed it when the jumper was put back. This is the point where the computer sets the advance.
Good Luck
