i just bought the car about a month ago. at first i thought it was just turning off randomly but after about 4 fill ups of gas i realized that every time i would get to a 1/4 tank my check engine light would turn off, sounds wierd, i am thinking that it is the fuel pump. i ran the check engine codes and it came up with egr. but why would it turn off everytime i got to a 1/4 tank.

maybe your gas cap is going bad. but im not sure if 240's throw a check engine light from their gas cap. i know more modern cars do.

Is your check engine light always on, and when you get to 1/4th tank it turns off?

Or

Does your check engine light comes on when you get to 1/4th tank?

Maybe a fuel pump problem? Fuel pressure regulator? Check all your EGR tubes and make sure they are secure/not leaking or cracked or anything.

the light comes on and when it gets to a 1/4 tank it goes off
my car is obd1 so its a little bit harder to reset it. also i have checked egr lines there all ok i just dont know what the egr code would have to do with the gas tank.....
