I can't see how letting the gas run, ect., would work. That would only
starve the pump and be hard in it.
One characteristic I did note as this problem continued on over the
approximately three month period, the gauge functioned as it should when
the interior and exterior temperatures were relatively low, say in the 60
deg and lower range. As soon as the temps starting going up then the
problem showed up. Now, the problem could have been caused by a bad
connection, intermittent connection, or losing ground somewhere along
the way. But, I VOM checked connections from FF sensor to gauge cluster
to wiring back to the fuel level/fuel pump connector. So being all that
was "good' the things to suspect were the fuel level sensor or the gauge
sensor or FF sensor. Easiest and cheapest thing to replace was the fuel
gauge sensor. And it made more sense to replace it since it had a
history of failure. If I remember right the factory wiring schematic
shows connections running from the sensor to the gauge and to the FF
sensor and back to the tank mounted fuel level sensor.
Ya' know, encapsulated electronic parts can be a funny thing. "Cold" and
bad solder joints can be there but they can't be fixed or seen if there
is hot plastic poured all over them during manufacture. And improperly
manufactured IC's, transistors, ect., can breakdown when temps start
getting a little warm. I suspect that was what was happening.
Hey, at any rate, it's still working good!
