Fuel Gauge question...

[spareparts]

go to the back of the guage and ground out the s terminal( pink wire should be hooked to it) with the key on, it should peg the guage, if it doesn't, make sure you have 12 V + (purple wire), 12 V - (black wire). If you have power and ground, and ground out the s terminal,then if the guage doesn't move, you have a bad guage. Take the sender out and hook an ohm meter to it, slowly run the flot up and down, it should change the ohm reading in a smooth flow, and jumps or o redings would indicate a bad sender
