540 fuel pump relay location

[barry 90 525i]

Still chasing my 95 540/6 rough running. Went and switched fuel pumps from my other 95 540/A that runs good. Now my 540/6 will not start,just cranks. Which relay is it. In the pass side box i have one white and 3 light green ones. i figure the white is main relay,but which green one is fuelpump. thanks

I thought the fuel pump relay was actually in the DME Box on the other side,no?

My box looks different. I have 4 relays in a row, 1 white, 3 light green.

Well like a idiot i had hooked up the lines backwards. so now the car starts up obut runs really bad still. So now i have switched the fuel pump, maf and replaced the plugs, car still runs bad. Next i will change the fuel filter, have to order them since no one carries the double filters. I dont believe they could be causing my problem,but want to eliminate them.
