BMW E30 320i fuel pump relay location?
 

Hi, i need help at finding fuel pump relay. Fuel pump is not getting power, when all the wiers are plugged in. Tester shows that there is little power in fuel pump plugs, put it is only 2V, but it sould be 12V?
It must be relay problem then? If yes, then can anyone tell me where i can find that relay?

It's not sur at 100% that's it's your relay, it can be your fillage too, did you chek with a volt meeter/volt mètre (I don't know the word in english). If you didn't chek test in (parralele) with your voltmetre around your relay and what your fuel pump touch too.

And I think that you can buy a relay in any electronic shop, you'll need the specs of your currents relay and that's it I think.

Relay should be in the fuse box, and it should be a big long/tall black one.

Hmm i think we found what we were looking, but still there is no power in fuel pump cable. There are 4 cables going into that outlet where relay can be plugged in. So we took tester, and looked that 3 of the cables have 12V power on it, but last one is empty. So relay should switch that last one, and give fuelpump power? And for conclusion its true that relay is bad??
