Need some help please, fuel gauge not working (below E) since I had an engine rebuild last summer - of course, they didn't cause it. But anyway, I disconnected the sender and shorted it with no change on the gauge.
The sender appears to be a reed switch type and with around 1/2 tank I see 143 Ohms on the connector so that seems reasonable. Put a DC meter on the gauge side of the sender quick disconnect expecting to see 12 VDC - nothing at all and can't be right.
Pulled the instrument cluster to find that my 2005 gauges aren't conventional - seem to be a 3 wire bus daisy chain probably from the computer. So now, what do I do? There isn't a fuse dedicated to the fuel gauge and all other gauges are working fine so this is either a wiring problem or the voltage source. Any suggestions please?
Thx, Ed
