Thanks, Art.

I did what you suggested, and the results are not what I expected.

First, there is battery voltage on the right side of fuse 6, if I connect a jumper from fuse 4 to the left side of fuse 6.

Then, there is battery voltage on the orange wire of the MAF sensor when ignition is on.

But when I pinch the return hose and have my assistant connect the jumper, I feel the bulge in the return hose. That I did not expect. Is this test conclusive? I.e. telling me that the main pump is working? Or can it be that the in-tank pump generates enough pressure for me to feel the bulge, but not enough for the engine to catch?

Thank you again.
