A bad ballast resistor will cause a no run condition, but not a no start as the resistor is bypassed while engine is cranking....it will start, but die immediately as key is released to the run condition, which does not appear to be the situation with the OP s car.


This is only true if the ballast resistor has only two terminals. The later ballasts had four terminals.It depends on which side of the ballast is bad. I have had this exact condition and it was a bad ballast resistor.

Agree with the removal of ballast resistor with msd.
