As I learned last week, it seems effectively the same. I guess you could
try grounding terminal 85 directly at the relay to rule out anything
specifically with the relay.

Would it be the case that pin 19 at the ECU should be continuous to
ground during intial startup and then cut out 1.5-2 seconds later, and
be continuous to ground during normal operation?

Is it possible that pin 19 at the ECU connector might just be loose?
