Its getting no power to anything it has a brand new battery and all the fuses are good, but maybe the ignition fuses under the hood what is could be the problem

If you have installed a brand new battery and there is still no power to anything when you turn the ignition on, there could be several possible causes:

1. Check the battery connections: Make sure that the battery cables are properly connected and tightened to the battery terminals.
2. Check the fuses: Check the fuses in the fuse box under the hood and in the interior fuse box to make sure none are blown.
3. Check the ignition switch: The ignition switch may be faulty and not allowing power to flow to the electrical system. Try turning the key to different positions to see if anything changes.
4. Check the starter: The starter may be faulty and not engaging. Try jumping the starter directly to see if it turns the engine over.

If none of these steps work, it may be best to take the vehicle to a mechanic for further diagnosis.

Check fuses, grounds and /or follow the positive cable until you find where it's disconnected

main ignition fuse is only for just that...

if you checked that the circuit to that power outlet is OK, including the wiring, maybe the jack itself is bad

disconnect it, then use jumper wires to the battery to see if it powers on

I have found with these Crown Vic's,especially police cars,they manage when the get in accidents to hit the right front of the cars and when they do they damage the wiring harness. The rain,salt,snow get in the harness and you eventually have problems. Look under the car in front of the right front tire and you'll see. Good size wiring harness. Look at it for damage,or sometimes you'll see like a light green dust coming out of the harness. Usually where I find my breaks,shorts or opens.

Yo may have a bad ignition fuse under the hood. Should be a big square box, pop the cover off and look for that fuse, maybe a gray square type fuse.

check the fuses under the hood.maybe ignition or just check them all.

CHECK BATTERY VOLTAGE ITS SHOULD BE 12.5 VOLTS.IF YES.I AM LOOKING AT BAD GROUND BATTERY CABLE OR LOOSE CORRODED BATTERY CABLES.REPLACE THEM IF THEY ORIGINALS CABLES.TURN OFF RADIO FIRST BEFORE REMOVING BATTERY CABLES.IF BATTERY AND CABLES GOOD.CHECK IGNITION POWER FUSES AND ALTERNATOR FUSE.IF ALL LOOK GOOD.YOUR ALTERNATOR COULD BE BAD OR A OPEN IN IGNITION SWITCH COULD BROKE OR LOOSE WIRE IN SWITCH.

check the ignition fuse under the hood and also check the ignition relay, if this does not fix it you probably have a ground problem if you are not getting any power to anything

check there should be a fuse box under the hood are some small little black are green boxes under the hood one of them is your fuel pump relay.
