Can you probe both wires and see if you get continuity or whether it is cut and grounded out somewhere? My harness had a cut and occasionally shorted out.

ECM grounds injectors strings. No ground at ECM pin either connector or ECM. Also verify 12v and ground to ECM. Connector terminal wire can break (copper part) and only the crimp on the insulation attaches terminal to wire.
