Before you give up on it, try this. Cycle the e-unit until you get to a spot where the engine should be running,(not neutral).With a toothpick, push on the fingers to make sure they are making contact. I had the same problem with a 302 and it was driving me nuts.I asked Don Roder, owner of GarGraves Trackage, and whom I consider a friend,what I was doing wrong. He told me even though the fingers look like they're in contact with the drum, they might not be. Sure enough, that was the problem for me.
