Problem with remaining fuel gauge -ford focus 2003

I think something wrong with your ford, you can use a autocom cdp pro cars diagnostic tool check your car,

Bad sending unit in tank or defective gauge.

I would check the fuses first...........This is usually the problem.....Hope this helps.

check all ground wires,and the plug behind the gauge cluster-

new dash unit complete i think

Check the lights on the 3rd brake light. If the bulbs are out the brake lights will remain on when in gear, but work properly when in park. I had the same problem had to go to Napa to get bulbs (5) and now all is fine.

With the sensor unplugged and the fan works,, replace the new sensor,,,,, it is probably defective. I have seeh this before.

In my opinion it sounds like a problem from inside the fuel tank but don't quote me on this. With multiple sensors and switches related to fuel movement throughout the vehicle you're truly better off having a professional deal with this, unfortunately it will cost a few dollars.

yes they do and you should have a fuse panel on the drivers side on the left of the steering wheel and there is also a junction box under the hood.. please rate this

A common problem on the 2003 focus are the electrics, i had a problem recently where the displays where not functioning, i took off the panel, checked the iso connector and before putting it back in i gave it a quick spray with wd40 and it al seemed to work, been in contact with the garage and for a new unit with callibration you are looking about £140 or so with labour and parts
