If it has the turbo script on the rear deck, and the boost gauge in the dash, there's a reasonable chance it was a turbo car. The Turbos also had different brake calipers and other parts. Check the VIN, and check the inside of the fender flares to see if they were welded on, or one piece. If it was a turbo car, ya really stole it!

Further suggestions:
1. Put an inline filter between the tank and the fuel pump. It will save the pump. I'm pretty sure the 77 has the fuel pump under the front of the car. You should look for an inline filter that has a right angle on one end to make it easier to adapt to your fuel hose.
2. When you swap the old fuel hose, do not buy the made in China crap. Most of the FLAPS sell Gates or Goodyear brands by the foot behind the counter.
3. It sounds like you can do the troubleshooting, so check for fuel pressure and flow at the engine by removing the connection from the filter to the fuel rail and putting it into a container. I forget what the spec is, something like 2 quarts in 30 seconds. look it up to be sure. After you verify adequate fuel flow, then disconnect the return line from the fuel rail and check for plenty of flow.
4. Hold up the plate/arm and try to start it while holding it up. See whether you can manually get it to run.
5. For future reference, Pelican sells a genuine Bosch fuel pump for about the same price as the NAPA pump. If the NAPA pump dies, get the Bosch one.
