Fuel pump relay

[Olimk1]

Got a Fabia mk3 1.4tdi 3 cylinder which won’t start, turns over fine but doesn’t fire up. 
Doesn’t anyone know where the fuel pump relay is? I searched but cannot find an actual location. 

fuel pump is fine as it works when I connect it to a battery but no power getting to it when the key is turned. 
thanks

Location 1b houses what's described as 'fuel pump encoder'.

So I’ve removed the relay and checked it and it works as it should, checked the others too and all seem fine. Fuses are all ok too. 
any other ideas why fuel pump wouldn’t be working?

I'll pop back to the circuits for a look-see.

Engine code would be handy.

Engine is cusb 1.4tdi 90hp

Ta, so check engine bay fuse no. 14 (10 Amp), which supplies the coil of that relay amongst other things.

 

Then cabin fuse no.49 (25 amp) which is power that the relay switches to the fuel pump.

 

If both of those are OK it may be that the engine ECU isn't grounding the other side of the relay coil 'cos it's unhappy with something.

Ok cheers. I’ll have a look at all of those tomorrow
