    Does anyone have a pic of the contacts under the black cover... ?
    Pump shaft appears to need an eclip/bar to pull the lower contact away from the top contact when no power is applied. I can cycle the pump by jumping the blk/grn str wire to the positive terminal and touching,removing,touching ,removing... while I have the grn run to a ground or negative terminal.
    Someone else removed the pump when they thought it was leaking and took the back cover off it.....
    right now the spring has the lower bar pushed up against the top contact, and that is where it stays as removing power causes the shaft to retract back, but nothing to pull the bar down and remove contact from the upper contact.

    Thanks for any help on this.

    Got it !

    Found a pic of the contact set on wemoto.com, the answer was front and center (or top as it was). the one contact 'flange/pivot point' was not in the slot for it. when I moved it up into it the 'spring bar' moved right up into the groove on the piston. Now it pumps like a new one again. I cleaned up the contacts as long as it was out.
    Jumped it, ran until fuel came out, put my finger over the end, it slowed and stopped. plugged it all back in and it started right up, sat 2 years. God I love Honda products.

    My father had pulled it as he saw some fuel coming out in that area (it was -20, he is 73 and retired with nothing to do in the winter). I put it back in and have not seen any fuel leak since then, so I am hoping the extreme contraction of something opened a small area for it to seep....
