I need to know because my fuel pump for my unturboed wagon just crapped out on me because its hardwired to an accessory lead. I think it can't stand the constant power when its at idle. So I need to know if I where to hook it up to the turbo plug at the back of the car if it would even work or not? I do not have the ecu hooked up. I'm hoping its controlled by the disty advance somehow but i'm not sure. I also need to know how the ea81 n/a is controlled if its the same way or not? Any help would be great! Please help me!:-\
I forgot to mention I did swap out the fuel pump when I did the swap with a n/a fuel pump.

The fuel pump on the '82 Brat I had was wired directly and it seemed to work fine. I don't recall were it was wired to.

So might it have been a cheapo crappy pump? It was pretty loud.

When the engine is running, they are always powered. Did you replace the pump with a carbed pump? They are VASTLY different pressure wise...... the turbo pump should not work with a carb anyway - the pressure is so high it would flood the carb out. Get a Carter electric pump from summitracing.com or something.

Ya I replaced it with one from a 1986 rolled carbed hatchback.
