Hi there I have a 2002 ej205 Subaru Forester s turbo sf5 it has a denso 1u ecu White 5 plug works fine but I bought a denso v3 ecu White 5 plug from a Impreza wrx not sure of the year I also got the ignition barrel imobeliser chip and little black box from steering column when all fitted it turns over but won't fire up and I don't hear my fuel pump priming put the forester parts back on I can hear fuel pump priming on second click of ignition and fires up fine I was wondering if use could help me please thanks in advance
Also my car has a sigma cat1 alarm/imobeliser fitted of that makes a difference thanks again.

have you compared the wiring diagrams of the two ECU's?

If you've changed from UK ecu to jap ecu the crank and cam sensor are the other way round

There are much greater differences than crank and cam sensor wiring ... thats GC8 level differences not GDA/GDB

Keys need to be coded to the ecu as well

cheers
