1. Make and Model of your Car
2000 Chevrolet Impala
2. Include the mileage
about 75,000
3. Automatic Transmission
4. 2 wheel drive

7. Past repair history if applicable
I just replaced the battery.

My car went into the dealership for about $3k of body work from a recent accident. When I got it back, it took a while to start and made a weird clicking noise. However, I got it started and took it to Murray's. They ran diagnostics on the battery and the cell was dead. I replaced the battery and everything seems fine. When I turned on the car, I noticed that the fuel gauge (registered at E), temperature controls, speedometer, odometer, and gear (P/N/D/...) aren't working. I think I might have blown a fuse, but I'm not sure which fuse to change...if it something else, please let me know.

After 3k in repairs...I think it should return to the shop! May need a new body control module...or instrument cluster! Both are expensive...! Depending an what they did as far as repairs go I would check all connectors, they may have not gotten something plugged all the way in

I took it to the dealership, and it turns out that something was unplugged in the dashboard....but I had to pay for $100 for them to plug it back in.

Fuel gauge not working properly,most of the time reads full but sometimes moves up and down even when sitting still.Possible it has a bad ground?Is sensor intigrated with the fuel pump?

The fuel pump and sending unit are in the same assembly. You do need to check the ground, a loose or corroded connection at the ground connection can cause all kinds of problems. It you end up taking the fuel pump assy out, you can bench test the sending unit using an ohmmeter. Connect the lead to the ground connection and to the sending unit connection, move the float up and down and see that you have a good steady resistance change in both directions. If you have areas that are not reading then it is time to change the assembly out.

the gas gauge pegged out last week to where it is touching the temperature gauge. But the low fuel light will come on alerting to low fuel.. Last year had rust in gas tank and had tank dropped and cleaned no
Problems until now and this was after the tachometer gauge quit

This is a common problem with this model, it will need a instrument cluster rebuild kit,

Some companies such as AER in Brea, California will do it for you, if you send it in.

Here is more info, we did a video on how to get the cluster out.
