Four out of 6 injectors were clogged from old gas. To get the internals moving again I hooked up a wire from the battery to one injector prong, then another wire from the other prong and dragged the other end along the rough plenum surface back and forth. Getting 12v to the injector jumped everything loose and she is alive again! Going to drop some Seafoam treatment in the tank tonight. (Thanks to Kevin at Z Clinic for the idea)
