This happen to me 2 weeks ago brother, and boy it was a pain in the ass. I had my mechanic fix it. There were alot of possible reasons why it didnt work and my mechanic narrowed it down to being the fuel sensor and the fuel meter on the cluster. I had to replace my whole cluster because, you couldnt just get the fuel meter and replace what you have, the cluster is 1 by itself, so you would have to replace the whole thing. Hopefully for your sake, its just the fuel sensor. Or perhaps its just a fuse, check that one 1st. Good Luck Man!
