cannot get gas panel wont open

If the button has power to it see if the button is bad (may have to run touch a jumper wire to each wire to make it operate or touch those two wires together or find the fuse blown for it and change it out) if good have someone push button while another gives the Fonzy Jab on or near gas door panel.

Look in the trunk left side against the side there will be a cable that will open gas door
