I read the sticky in the C6 tech but that doesn't seem to apply to the ZR1 (the jumping of the pump relay)

Other than loading up a tune via HP tuner to trigger the prime for say 30 or 60 sec a a time, how can I manually turn on the pump? (end goal here is to empty the tank)

This is how i do it on my Z06, not sure if it works the same on the ZR1.

After re-reading your post I realize you already figured out this won't work for the ZR1, I apologize.

ZR1 has a separate fuel pump control module. Use your Tech2 (or Nano, or MDI, or whatever) to command the pump on.

That is neat! On! Off switch, where did you get that from?

Do you have a mechanic friend with a power probe? Just give it juice at the pump.

I figured the fuel pump control module would not make this easy....
I ended up hooking up my hpt and set the fuel prime to 120 sec. Did a couple on/of rounds and I got 8 gal out in no time.
