WD40 is much safer as a starting aid.
The WTS light is not tied into the glow plug circuit. If the WTS light is not coming on the PCM is not going through its self test. Either due to a blown fuse, blown bulb, defective PCM.

I also have a feeling the PCM has problems.
You need to have it scanned for codes and see what comes up. If it comes up with glow plug lamp circuit, the pcm may be fine.
If you can't get the scan tool to communicate or get a rom error, it could be a fried PCM.

A PCM from DP is far cheaper than a dealer unit and performs better. Do what was suggested with the SC support and post back.
Good luck.
