Chrysler Concorde 2000 fuel alarm going off

My Chrysler Concorde fuel alarm started going off. It goes from full to
empty on the gage and an audible alarm comes on and goes off.

Fuel tank is full. Just filled. Fuel cap appears to be on okay. Took
it off and put it back on.

Can I safely drive this car. Is it an just alarm malfunction? or what?
Could this be bad gas? I just need to know if I can drive it to my
local dealer Monday morning.

Thanks
Paul

 

Paul, the fuel sending unit is bad causing this to happen, the fuel pump has
to be removed from the tank and a new sending unit will have to be
installed. If this vehicle has a lot of miles on it you may want to have the
complete fuel pump module replaced. The pump is about $400 and they may
charge about 2 hrs labor to install it. Same labor for the sending unit but
the part is about $150
And yes you can drive your vehicle as long as you know how much gas is in it

Apparently high sulfur gasoline can cause fuel sender malfunctions as well.
There was a problem with Shell gasoline a few years ago due to a production
error, and the company paid for a lot of sender units. Symptoms included
malfunctioning fuel gauges and low fuel lights. The sulfur corroded silver
contacts. I recall that Chrysler products were especially susceptible. May
not be your problem but something to be aware of.
