Jeep wont start , oil was low so accidently put too much oil in it, battery is new, what could be the problem?

Take spark plugs out and see if it will crank over. It may have gotten a hydraulic lock due to the overfill of oil. With the spark plugs out it should purge out the hydraulic lock on oil if that is the case. Or it may be the starter.

Did you replace the oil pan? many new cars have an oil level sensor and will not start if they read low oil so as to prevent the motor from seizing from too much heat and friction/wear.

some of these models have a fuse box on that side under the hood. I'd start there first. After that, have an assistant try to start vehicle while voltmeter is attached to battery terminals. Did voltage drop to 10-11volts during cranking attempt? If so, suspect starter.

Add oil. Check your Brake lights. If they do not work, the problem with starting is the brake safety switch. You are required to put your foot on the brake pedal to start your car.

If the brake safety switch is broken or knocked loose of the holder on the brake pedal lever, you will not get the release signal to engage the starter.

Check Neutral Position Safety switch.

low oil on some models will stop it from starting however I would say you have a fuel filter stoped up this happens sometimes when you run a car out of gas they pick up trash,

You might not believe this, but check your battery. Some of these vehicles have cut-outs when the battery level goes below a preset amount.
I work on Ford brands and on them, a low battery level will even disconnect the Alternator circuit and mess with the starter. Some even act up when the battery slightly dips below 12 volts.

Your antitheft can make your starter cut out. And If you think about it, all of the measurements to make the engine run are based on feedback of voltage and amperage. This is how the engine management system adjusts. If your prime source of power is low, then all of the following electrical readings will be low. Some may be too low to work.

Your fuelpump will hold pressure in a closed system for hours. The fuel pressure regulator will command the fuelpump to stop working if the fuel pressure is at maximum. Without responses from the other components and after satisfactory pressure, the fuelpump will turn off.

check the fluid. with it running and the wheels block or a friend in the jeep put it into N. make sure your on level serface and put the trans dip stick for the oil level. in may very well be low on oil.

did you install the oil pressure switch origional to the tahoe? The tahoe uses a low oil pressure shutdown, instead of an inertia switch to shut off the fuel pump in the event of an accident. If the pressure circuit does not close within 3 seconds after the engine starts the fuel pump shuts off. This is in case the truck is on its side or upside down the pump will shut off.

Put a volt meter on the battery. You should have at least 12 volts there. If not, recharge the battery and re-check the charging system. Some systems have the voltage regulator as an integral part of the computer. "full fielding" the alternator tells you the alternator is good but does not tell you if the regulator is working. You also need to check for electrical drains on the battery when the engine isn't running.
Of course, put oil back in the engine if it's low, but that should not keep it from starting unless somehow you have seized it from a no oil condition. If you can turn it by hand, that hasn't happened.
