I had another issue with a motor that I thought the triggers were reversed, I did multiple cable re-wire worked on it for 5 hours before I loaded the car on the trailer and I talked to the magical Mel, he said swap the triggers which I did (prior to that I had swapped the wires how many times) and swapped the wires in the plug to the box again for the 10th time to match the swapped triggers and it worked. PFM was my only answer. Wish I could be more help full, but if you do not have more MPEM's or triggers to swap out, I think Cory has the best answer, at least Mel will be able to swap it all as needed to test it out.
