need good voltage for this ignition relay to work...make sure that you've got a solid 12 volts at the chassis...get a NEW battery if older than five and wirebrush the end of the black cable (not the clamp end) the one that goes to the chassis/ ground....wirebrush that connection betweeen dis-similar metals~
