Probably not covering ground you haven't thought of, but I would go back and re-touch everything you d/c when you pulled the engine, or anything that might have gotten knocked loose. Loose or intermittent connection is where I would be focusing my attention. I agree with checking function of the dual relay (manually opening the flapper door) and then, if needed, directly checking the relay. It would be an odd coincidence to have it go out right at the time you pull the engine. These are getting hard to come by again, but JBugs and CIP1 currently show them as being in stock. Unfortunately they cost nearly twice as much as they used to because of tariffs.
