my fuel guage dosent work i got to find that out the hard way today how do i fix this or test it to see if it can be repaird im in need of help plzzzzzzzzzzzzzzzzzzzzzzz this realy sucks.
well idk how it is on cars without a chip, bu on newer cars it ussually means dirty fuel clogged the sensor which would eventually lead to you needing to change your fuel filter etc, thats just my 2 cents, hope it helps somewhat
In no way shape or form will a clogged fuel filter effect your gauge. The gauge gets it's reading from a sending unit. The sending unit is a a variable resister. The resistance rises or falls just like the float attached to the sender. The BCM then sends a signal to the gauge or electronic meter. There's a tad more to it than that but that about sums it up,.....
dirty fuel clogged the sensor , said it ussually leads to having to change the filter not that it caused it, as far as BCM goes i have no idea what youre talking bout there, so feel free to educate me
well i puled it out cleaned it replaced filter tested wires at unit but still nothing maby guage?? it says nothing doesnt move???
Mine quit working and it was the ground. Jump the 2 terminals on the plug at the sending unit and see (key on) if it works. Should go to full, if not then ground the gauge wire (try 'em both) and see if the gauge goes to full. If the gauge goes to full after jumping the 2 wires at terminal I'd say bad connection at sender or sender. If the gauge works only when using an alternate known ground then it's probably a ground issue. If the gauge still don't work then it could be a wiring issue or gauge. If you have access to an OHM meter you could check the readings at the gauge.
You said on newer cars. A BCM is a Body Control Module. A sub-computer on todays vehicles. I still have yet to see any contamination of gasoline cause a fuel gauge to cease to function. I suppose if a pound of dirt found it's way in there but otherwisenot yet......
