Old Harness did not have the diode update, however I purchased a different solenoid from NAPA per R&S Performance recommendation, and that solenoid had a diode in it. Plus, the ECU (I thought) does not really deal with high voltage directly, so how could a damaged ECU blow fuses? I am gonna check amperage this weekend by the way, what kind of reading should I expect?
I wonder if on your old harness was the diode update in it?If not ECU could be damaged.Do what Wistech said also look at those little wires on fuel pump to see they arent wore through from rubbing on frame.Your fuel pump isnt running all the time?Your using a Pingle Kill switch?
I believe that issue is fixed with new harness but now he blows fuses.Is that right?
That Is Correct!
