This week's puzzler-84 Ti LONG PUZZLER! 200 1984

You should have power there (fuse #5) IF you have a pulsed signal from the ignition system. So just having the ignition "ON" will not necessarily make this circuit live, otherwise your fuel pump(s) would run all the time.

I will make this simple: Please turn to page 240-8 in your Bentley. The fuel system electricals are pretty easy.

Yellow-red wire at fuse #5 is for the in-tank fuel pump. I suspect the black wires are grounds. I dunno about the greens.

#30 on your fuel pump relay should be on ALL the time. That big red wire comes from the battery via fuse #7 (as I recall) and is the main power source for both fuel pumps.

I also suggest you get the electrical schematic out and start troubleshooting.
