Circular cracks sometimes form around the soldered pins of the relay circuit board. Usually around the pins of the heavier components mounted to the board. Heat can cause expansion of the board and change of grade (level) can also cause the heavier parts to shift and open a crack thus losing contact and fuel supply.

Open the relay and inspect the back of the board with a magnifying glass. Look for a circular crack in the solder around the pins that protrude through the board.

To repair the relay you can touch up (reset) the solder with a hot iron or you can get a new one from Phil.
