There are a few devices that use TD signal from the ignition, Make sure that one of these arn't shorting to ground.
Good luck and post your fix

Mike, Great checklist, as this appears to be a common problem, is there any chance of expanding on the methods to check these parts. Would assist me and others in tracking and eliminating possible faults. Thanks in advance.
