I do not recommend the "just throw parts" at it theory. This can be very costly and frustrating in short and long term. I have seen this happen. People throw parts at stuff, and it would have been cheaper to have it diagnosed. Granted finding someone who will actually diagnosis something and do it correctly is not easy. I personally like diag. way more than bolting on parts. Diag. is interesting, bolting on parts is boring and at times a PITA.
That being said, I recommend getting a GM Field Service Manual and learning about your Corvette then using the manual as a guide to help diagnosis your Corvette, when things go south.

You can jumper the terminals (I believe terminals 2 and 3 for a 86) of the fuel pump relay connector, supplying bat voltage to the pump, causing it to run until the jumper is removed. The pump should pump the fuel through the return line at the tank and fill the container.

Disconnect the fuel return line rubber hose at the fuel pump access plate. It should be the one connected to the rigid line which is at the lwr l/h (7 o'clock) position below the filler neck. Attach a longer hose to a suitable container to the rubber return hose.

In doing a little more research, I found another thread where Agent86 posted a link to wiring diagrams.....

Looking at Pg 3 of the prints, you can put 12 volts on Pin G of the ALDL connector and the pump will run. If for some reason that doesn't work, then jumpering terminals E to A at the relay will accomplish the same thing..
Thanks Agent86!

Your fuel pump relay should be on the firewall next to and a little below the w/s wiper motor. If you are going to go there, take the connector off the relay and use a small jumper wire to connect terminals a and e. - pump should run.
If you are going to the ALDL connector, make a longer jumper wire and go from the positive bat terminal or the jump block where all your fusible links are connected to pin g of the aldl.

If I get nothing, would this be an indication it's fuel pump related?
Thanks!
