This has been killing me a long time. I have a non- turbo 82 that I got running after I had unblocked the sender unit. Then I let it sit unstarted for a month as I did body work to it. It doesn't start now that I discovered that a cat for something had ripped 1 of the 2 wires out of the fuel pump. Now I have bought a new fuel pump replace the fuel pump relay under the dash and in the engine bay. But it still doesn't pump fuel. I am now ripping the car apart looking for a fuse as diagrams in the manual say there is in part of the circuit but doesn't give to any clue to where they are. :'(
