check for shorts on the coil- line on your tacho, the only thing to stop the engine from working would be if the coil- was being held at a constant voltage.
the ballast resistor in the coil+ shouldnt have an effect on the tacho.
hope that helps man, unfortunately i havent built a PIC based tacho, so i cant help much beyond that.
