Hi, my fuel gauge is not working consistently. I have changed the cluster as well as the sending unit but still have the problem. Please advise.

Regards,

Hi,

When you say it doesn't work consistently, do you mean there is no response from it or is it providing the wrong level?

Also, I am not finding information on a 2010 Spark. Are you located in the US?

Let me know.

Hi, Joe,

Yes, I did, it was just a bad connection caused by corrosion at the PCM and relay.

Bernie,

Thanks for the update. That can certainly cause problems. I'm glad it was an inexpensive fix.

Regardless, feel free to come back anytime in the future. You're always welcome here.

Take care,
