Do you mean the pulldown is not working, or the trunk lid latch is not connecting to the pulldown assembly when you try to close the trunk?

This latter case typically happens when someone slams the trunk lid down several times not realizing there is a pulldown system and thinking slamming it will make it close (this often breaks something). Check the latch on the trunk lid - if it's in the closed position, use the key to try to move it to the open position and try gently closing the lid again.

If not, there is also a switch on the pulldown assembly that starts the pulldown motor when it is depressed by the closing trunk lid - you can also check this to make sure it's working. Otherwise, either the latch or the pulldown assembly has been bent/broken.

The fuel sending unit in the gas tank is bad and you will need to replace it by dropping the tank down and pulling the fuel pump housing out as it is mounted on the side of the assembly. Run the tank low as possible if you pull the tank off and there is a inspection cap on top and you can remove the assembly after disconnecting the fuel lines and wires on top of the tank. Hope this helps.

What's the voltage reading at the battery with the engine running ? 13 to 14.1 volts ? If not, it's not charging .Sounds to me like it's not charging ! Is there battery voltage at the heavier gage wire on the back of the alternator ? Does the battery symbol light on the dash work ?
