It was an auto-electrician who found it and I haven't seen it yet but understand that it's a simple relay, connected such that the PCM provides the ground signal to operate it.

The relay was found to be in working order, but the problem is that the PCM isn't providing the ground signal. The wire from the PCM to the relay is intact.

On the surface, it would appear that the PCM may be faulty, but that assumes that the appropriate input signals are being received by the PCM. At a cost of nearly $2200, and considering the age of the car, replacing the PCM is out of the question; it would be far cheaper to install a 'cold start' push button switch to manually operate the glow plug relay.
