I have a 2003 cherokee and the check engine light keeps coming on. Ive had it reset twice and place a new gas cap on but it keeps coming up as a large evap leak. Also when i start the vehicle when it is cold a steady succession of beeps comes from the gas tank area and stops after a minute or so. Could there be a comon link between the two. Because of the check engine light i wont pass a vehicle inspection. Any suggestions ?

Thanks
