Hello
I know you use the red and blue wire from the ecu but do I run it straight to the pump or should I make a relay circuit for it ?? And if so how ??

The red/blue should already be coming from the fuel pump relay in the loom !

Unfortunately there is no fuel relay in my loom because the person before me butchered the hell out of my loom :(

sounds like you need a new loom

Aww I hope not because I need the car done hahaha I am going see what else I can do!! :/

But am I also right in saying that no fuel isnt going to effect it sparking ??

it should spark regardless of fuel... you could connect a small light to the fuel wire to see if it powers up.

going with the above, you need the relay to drive both the pump,IACV, the injectors, EVAP SOV (if used) and the heater for the lambda. Wiring all this off the ign switch without a relay will be almost certain to result in spurious fires.
its 2 relays wired back to back by the looks of it. you could wire 2 individual relays the same way if you do not have the GM relay (A171)

all the wiring colours are there so its easy to work out what you have on the loom, to what you need.

Cheers guys is that the code for the relay because I might just go buy one from vauxhall probably and make it back too factory loom..... Easier sellability when I get a let ;)
