Is 12 volts getting back to the pump for a few seconds when the key is
turned? If so, and the pump isn't running, check it's ground lead
where it connects to the body metal, which can be a rediculously long
way away from the pump. If 12 volts isn't showing up, are you sure
the main relay's fuel pump relay is closing? If it isn't, check its
ground, which goes through the ECU and and is finally grounded on the
engine block on most Honda products.
If you don't own a voltmeter, use a 12V lightbulb and a couple of
wires,
If you plan on doing much work on your car to save money, a shop
manual is a wise investment. Honda manuals have logic diagrams to
follow when fault finding this sort of trouble..
