ECU problems

[Robb]

i've just hybrid' my clio. i bought a phase 1 ecu and gunner chip to go with it. the engine turns over but the fuel pump doesnt prime. my original phase 2 ECU works fine with it but its obviously not good for it. i think my loom is a phase 2. it has 4 purple wires in the relay box?

i think theres a spark with the gunnerchip but theres no fuel getting to it. Is just a simple 12v wire to it to get it to work? I have a third party alarm/immobiliser but i dont think thats the problem as its turning over.

Any help would be great

thought all the ecu,s worked except that the later ones had immobilisers.

could be your third party one though as they just stop starting not always cranking.

well it turns over with the gunner chip but doesnt start. when the immob is enabled is doesnt allow it to turn over... :( not sure what to do?
