Glow Plug Problem

HI,
I have a "no start and no wait light situation."

See below

Ok so I did more testing and I'm at a loss.
Heres the situation:
When I turn the key, I get no "wait" light and the glow plug relay does not engage.

What I've tested:
Removed the module, turn key to run, ground blue lead. "Wait" light turns on.

Turn key to run. Disconnect glow plug switch. "Wait" light does not turn on.

Electrical troubleshooting malfunction #15

1. Passed. Near 12V while starting.
2. Passed. Relay clicks and energizes.
3. Passed. Wait light turns on.
4. Passed. Near 12v at wire.
5. Passed. 12V present.
6. Just over 800 ohms
7. Passed.
8. Passed.

Are these results saying the GP card is bad?
I installed a new antenna climber glow plug card on Feb 15th this year.

I was able to speak to antenna climber on the phone. I'm going to send him the card. This is solved for now, I will update when he tests the card.

Edited to add. Antenna climbers cards are the best and his service is second to none. Don't take this thread to mean his cards are problematic, because they're not.

My card from antenna climber tested out fine. I replace my temp sensor and everything is working great again. I'm still confused how the tm diagnosis procedures didn't point to this. Antenna climber suggested i get a new one and booya. Antenna climber > TM???
