hi, hopefully somebody can enlighten me. I was recently working on my car ( nothing major) but I needed the ignition on and off then I left it on and battery died. jumped the car drove around the block and its fine BUT the fuel gauge stays on empty and the warning light for low fuel stays on.

any solution or causes known to this? all help appreciated.

cheers

Wow, that is strange. Can't help you but... on most older Foci that system is dead simple. A 2-wire circuit that goes in-between the fuel tank and directly back to the instrument cluster. Based on this, and if your car is designed the same way, here are my guesses;

1 - Defect with the instrument cluster
2 - Defect with the fuel quantity sensor inside the fuel tank
3 - A wiring problem in-between the 2 components above

If I was you, I would disconnect the car battery for 10 minutes and pet the car gently and say nothing but nice words to it. Then reconnect the battery.

thing is it only happened after the battery died so I doubt any of those issues could arise from that.... BUT you never know haha. I will for sure pet the car nicely ( I am getting a new battery anyway for winter)

Maybe not from it dying, but the Jump-Start coulda' pissed-off somebody inside that circuit. Disconnecting the battery for awhile might bring the moon and stars back into alignment.
