Yes the Glow Plug Relay (GPR) has a high failure rate like you experienced.

If it happens to you again then you might want to do what many of us have done and replace with a “larger” Stancor (White-Rogers) GPR.

You can buy one at Diesel O-rings:

If your 7.3 would start after being plugged in then your CPS was probably still “good” so you might want to keep it as a spare in your glove box with a 10-mm wrench.
