2001 Ford Taurus ses  not starting no sound or click at all check engine,battery and gas cap light and transaxle light don’t come on ?

Ok so I have check to make sure the ground connection was good I charged up the battery I replaced the starter but no that’s not it u know when u switch your car to the on postion all the warning lights suppose to come on before starting right, like what I said above those the only lights that don’t come on my last resort is that my ecu/ecm is fried or gone bad I did what everyone told me to do I just charged my battery maybe it gotta be fully charged ? It’s been on the charger since yesterday 1pm so I took it to see if it would start nope 🤦🏽‍♂️ I checked the fuses it’s good but when I trie to start it my friend hear clicking noises coming from the fuse box so we switches places every time he tries to start the car I hear clicking noise coming from it so maybe something is stoping it idk the guy I got to look at it he don’t know what he doing first he said this and that and I’m just like ughh I just want this car fix Ik Ik I gotta get a mechanic that knows the electrical problems I’m a car

Have you had transmission problems? Could be a faulty neutral safety switch.

Have you checked the ignition module It's a no spark No nothing failure of the ignition module also check the fusesible link on the charging circuit if that blows same thing you get nothing interior ad far As lights and no exterior lights either no clicking on the starter YOU GET ZIP when those two things fail on a older Ford

ECU is fried or there is a bad ECU ground or a sensor/s is/are shorted or there is a bad sensor ground.  Check all the ignition fuses.  Check for a bad ECU ground.

You can connect one end of jumper wire to the S terminal of starter and with key On and shifter in Park, touch the other end to battery positive.  If engine cranks but does not start, there is an issue with the ECU/sensors.  If engine cranks and starts, you are lucky and you might just have a bad ignition switch and a bad cluster.  Good luck.

Do the headlights work?  If not, measure the battery voltage. You can charge some bad batteries for days and they still don’t work. A fully charged battery should read about 12.5 volts with nothing on. With the voltmeter still reading the battery voltage, try to start the car. If it goes way down, you need a battery.

have someone check to see if the brake lights are ON when you step on the brake pedal, because the brake light switch is part of the transmission - ignition interlock system ..........
