That pump is not going to prime without an engine speed signal. They don't buzz the pumps until LH 2.4. I'll look at my schematics when I get in to the shop in the morning and see why you are not getting an amp reading on the main pump. Obviously the darn thing is working or the car would not start. Another down and dirty way to check that pre pump is to put the car up in the air and pull the feed line off of the back of the main pump and bump the key. Does fuel kind of roll out the end of the hose or does it barrel out like a race horse? It should be obvious we are looking for the race horse response here. I have seen pumps with a good amperage rating that were not delivering the goods or they had a torn hose and were spewing fuel everywhere but to the main pump.
