Duster Roars but wont start...help !

It should not be grounded if "we" are thinking of the IGN 2 wire. You ARE talking about a factory wire?

The IGN2 circuit only goes one place........from the IGN2 contact on the ignition switch to the coil+ side of the coil, originally the coil + side of the ballast. I suggest you unplug the ignition switch connector, and unhook the wire from the coil. Check it to ground should be infinity (open).

Maybe the switch is bad. "I've heard" of them breaking apart internally. You can easily check it....accesss the connector there at the steering column.
