Default thermostat housing ground?

Where on earth does it go? My car does not have one and I continue to hear that I need to check it.

Fuel pump is not priming and main relay is clicking (repeatedly).

G101 for the 5th gen Accords is located on the drivers side end of the intake manifold upper plenum. It is connected to the lower right hand bolt that secures the vacuum boost chamber (hose fitting block) to the plenum.

I think that is what I am missing. Does the ground come out of the wiring harness?

I'm pretty sure it does, it's been a while since I had my harness intact. IIRC there are 3 wires, 2 brown and 1 black, they are a thicker gauge than the rest of the harness wires.

It comes out of the harness, will have 4 grounds on it going to the same circular hoop. on some motors seen it on the rear of the plenum, some onm th therm housing... EITHER WAY IT HAS TO BE THERE. It is al;l the grounds for the ECU. Your car will not run without it. Ive had mine even come loose and had it cause all kinds of breakup issues and whatnot.
