I have a feeling that I know what the reply will be but, this morning I put an AVO on the pump connections and had 12 volts for about 3 seconds whilst the pump primed and 12 volts during cranking of the engine and for a brief period when I stopped. I could clearly hear the pump humming during the priming period and for a second when I stopped. Tacho needle is moving slightly also.
Are we looking at a filter problem still.
