The amal valve shares it's feed with the ISCV and fuel pump via the fuel pump relay, we know the pump is working so therefore this is working!

Contary to whats been said the ECU relay supplies the feed to the injectors NOT the fuel pump relay, you have power to your ECU and your injectors from what you said, the 4V sounds normal as the ECU pulses the injectors.

The above applies to the whole family, for some real geeky info the ISCV feed is moved on the 4x4/L8 to the ECU relay, not that this effects you.

I think the injectors may well be working, remember you only have the prime to get you started, it is only when the engine is then running does the pump run, so to me it makes sense that the plugs arn't going to be wet.
