I had a long alligator clip wire so used the negative battery post.

All pins on the ECU said O.L.

All pins on the connector said O.L. Except 5 And 16 (grounds) Showed .3 and pin 15 (ECU to FV to OXS relay) showed 4.2 ohms

Is the line between ECU plug and FV shorted? Or maybe the line from FV to OXS relay?
