Sounds like a short.
ACC on a car ignition stands for "Accessory." When the ignition key is turned to the ACC position, it powers the vehicle's electrical accessories, such as the radio, without starting the engine. This allows you to use these features while the car is parked.

It is the ACC fuse
For most cars, the sequence is... Off, ACC, Ignition On, Start
ACC is an acronym for Automatic Cruise Control. If you are getting an "ACC Reset" Message, you can try cleaning the sensors, or try pulling the ACC fuse and leave it out for about 30 minutes of drive time and replace the fuse. That mat reset the ACC in the computer.

where are the fuse
Look for "ACC" (accesory)
A fuse blow when ever the amperage is to high for the circuit. Either there is a short (to ground or positive), the connections are corroded, wire gauge is too thin or it is the wrong fuse. Never put in a fuse larger than recommend for the circuit, it could cause a fire.
i am not a mechanic but i would check to see the wires at the fuel pump have not been reversed, secondly i would check the power wire is not earthing out somewhere along the line because only a dead short can cause a fuse to blow. jacken.
look at the fuse box and find a acc circuit,If you have a test light check to make sure that the acc terminal you use is a keyed hot.When the key is on it will light the test light and when the key is turned to the off position it will turn the test light off.Make sure you use an inline 15 amp fuse.You can use a spade connector to plug into the fuse box acc terminal.THe ground wire can be connected to any metal bracket under the dash as long as it it a good clean ground.Most fuse boxes have 2 or 3 acc circuits.
