2002 mazda protege 2.0l
Hello, I have a 2002 mazda protege 2.0 The check engine light comes on when i get down to about a 1/4 tank of fuel and acts erratic. when i fill it back up the check engine light goes off. the fuel pump seems to work fine. Is this the sending unit or something else. Can i get just the sending unit or do i have to replace the full pump assembly with everything on it. Any advice would be appreciated
Thank you
 
The best thing would be to get/loan/borrow a code reader to see what is causing the check engine light to come on.
