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.
ACC on your fuse panel typically stands for "Accessory." It refers to a circuit that powers accessories in your vehicle, such as the radio, power windows, or interior lights, when the ignition is turned on or in the accessory position. This circuit allows these components to operate independently of the engine running, providing convenience and functionality. If you're experiencing issues with accessories, checking the fuse associated with the ACC circuit may be a good first step.
Ignition sensitive add -on accessories
In the 2016 Acura MDX, the fuse for accessories in the driver's side fuse block is typically the "ACC" fuse. This fuse is responsible for powering accessories when the ignition is in the "ACC" position. You can find the specific fuse location and amperage in the owner's manual, which provides detailed diagrams of the fuse box. Always ensure to check the manual for the most accurate and up-to-date information.
It is the ACC fuse
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.
For most cars, the sequence is... Off, ACC, Ignition On, Start
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.

where are the fuse
Look for "ACC" (accesory)
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.
