So I finally put my motor together and I am getting to fuel, the pump (walbro 255) was working fine before I melted two pistons. But now I cant even hear the pump when the car is in the on position. I have no idea were to go from here, can someone help me? Thanks!

***update*** so I put power to the black and red wire that connects to the fuel pump relay and I heard my pump turn on so the fuel pump is fine, now is there a way to test to see if the relay is working?

Just found this:
http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=FI&P=114

Now the relay is fine I did the "inspect relay operation" and "inspect relay continuity" but we seem to not be getting power to the relay itself , what can be the problem there?

Unless the wiring has been modified the pump isn't supposed to run when the key is at the on position, assuming that's what you meant.

Yes thats what I meant, I thought when the key is in the on position the fuel pump would then be primed? not sure though. Also does anyone have the diagram or how to check the Main fuse relay?
