Alright Dan. I've heard good things regarding you and wiring and I'm wondering if you'll take a read of my issue and maybe know what's happening with it?
I've just rebuilt th c20xe in my corsa b and fitted it, it runs fine however sometimes when I go to crank it over the ignition live for ecu gets very hot. I don't really know what's th cause of this, only on crank will it do this though. If you bump it then it'll fire sound and only sometimes will it do it at all
