RE: 944 injector problem

Replace the DME relay first. If the tach still doesn't bounce, then try setting the depth again of the reference sensor....it should be .8mm off the flywheel. If it still doesn't bounce, then i would bet money that you have a bad wiring harness. Cut the wires open on at the connection to the reference sensor (on the wiring harness side) I would bet you have some broken wires.
