Re: What in the world is wrong with my fuel pump
That sounds like the STVA clicking against the stops to me. I wonder why it only does it only sometimes, but it probably has something to do with the angle of the blades when the start-up routine starts. During the first cycle, for instance, they were probably closed from last shutdown, while on the second they were left wide open from the first cycle and, apparently, the ECM didn't bother re-cycling them. I haven't noticed such behavior on my K4, but, then again, I don't usually cycle power more than once before starting the engine.
