mine had a faulty driver transistor on one injector channel which was easily repaired its a BDX53C iirc - prob get them on ebay. that said, its unusual for 2 channels to fail at the same time as they each have thier own transistor. might have resulted from a harness short. was it working on your car or did you get it in faulty condition?
