Where's My Fuel Pump Ground?

Where's My Fuel Pump Ground?
I'm trying to confirm that my fuel pump is dead before I pull the tank.

No gas at all up front.
No buzz.
Relay is good.
12.3volts to pink wire in taillight harness for 3seconds confirmed with multimeter.

I just can't find the ground wire. Same problem as this guy:

Anyone know how I can confirm my ground is good to go?

RE: Where's My Fuel Pump Ground?
ok, the pump has 2 wires
the big pink wire you found that, and runs from there ( left tail) down to the bumper rear and to tank and is 2 wires.
the ground on the 4 door is not body attached at the tail lamp
it goes here, off my pump page there both photos, 2door and 4door (my pumps bad now what?)

here is the 4 door.
ground (its also covered i the full FSM book) it is called G300 in the manual.
as you see it cant fail much here, but will from here to the pump, it or the pink wire sure can fail.

Thanks!!

Ya, it looks fine.

Thinking about if I want to take it to the shop or try to do a new pump myself in the driveway.

Hmmmm....

RE: Where's My Fuel Pump Ground?
sure know the feeling well
the hard part is getting the tank drained, they made it as hard as possible.
there is check valve at the tank side filler into tank (roll over valve three, makes pumping tank harder)

I got her tilted down with all the tubing disconnected. One last electrical check at the pump for juice before I order a new pump. The disconnect is buried up inside the bumper. Grrr.

There's dried mud everywhere. Play you pay, I guess.
