Engine Loom wiring - VX220 blue, black plugs

Think I'm missing something here

I send 12v to x2 pin8 to turn on the fuel pump. I hear the relay click but the pump doent come on

I think this is something to do with the fuel cut off, and possibly because I'm not using relay K18 at all now... but I'm not sure what I need to do?

think K16 gets it's main voltage from the output of K18 (via the FCO). Therefore I need to set pin12 to 0v at the same time as setting pin8 to 12v

so K16 is triggering but hasn't got any voltage to switch

does that sound right?

yes the pump +12v comes through K18, you can either rewire the fuel cut off switch or keep k18
