hi guys, few questions/problems on a mk5b rs2000 '93'

1) what can cause the fuel pump to constantly run with ignition on
2) where and witch one is the fuel pump relay
3) what can cause loss of injector pulse, have pulse at coil packs so crank sensor is ok


also does anyone have a wiring diagram for the fuel pump circuit


really appreciate any help

 

any 1?

 

injector pulse (this is a stab in the dark) id go for getting the ecu tested as nothing else controls the fueling other than the ecu (EDIS does the sparks)
for the other things id ask on rs2000-16v.co.uk
