I went to go start my car today and the car started up the rpm needles on the speedometer jumped up then they went down and the car dies. When I try to start it again it doesn't even turn on just cranks over I tried taking the battery out and putting it back in but no luck the electrical works like the radio and all and the gas tank is full I need help on what it could be here is a video below please help any advice is good thanks in advance !

ONly time when mine did that was installing the F-sport Intake, the ECU had to learn the new air mapping. But then it started up back the next time without issues...
Perhaps a bad alternator was draining your battery and you had enough juice for one more start.... then it got completely drained. It could also be a bad ignition coil...

This is some ways to test the battery and alternator. (BTW you'll need a multimeter to run these test)
One Simple Battery Test:
1) Connect the voltmeter directly across the "Battery Terminals". (NOT to the Cable Clamps)
2) While watching the meter, Start the Car.
3) The Battery Voltage should Never fall below about 10 Volts.
If it does:
a) The battery is either "Low in Charge".
b) Or The Battery is "Low in Water".
(The water leven in the battery should be about 1/4 of an inch, Above the Plates.)
"DO NOT" Fill it up FULL.
c) Or The battery has a "High Internal Resistance".
(Possibly Sulfided Plates and probably Time for New Battery?)
--------------------------------------------------------------------------------
**NOW Repeat This Test BUT:
1) Connect the voltmeter directly across the "Battery Clamps on the Battery Cables".
2) This Reading should be Within 0.1 Volt Maximum, the Same as 3 Above.
***If NOT, Clean Battery Terminals and Clamps.
2a)If Necessary, Repeat Test to Varify it is now OK.
--------------------------------------------------------------------------------
**NOW Repeat This Test Again, BUT:
1) Connect the Voltmeter Directly Across the Positive Terminal of the Starter and it Case Ground.
2) If the voltmeter reading is More than 1/2 Volts Lower than the Previous Test,
** You Probably have a Cable or Connectorp Problem!
Check the Connections between the Cable and the Cable Connectors. ON BOTH ENDS.
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
One Very Simple Alternator Test:
1) Start Car and run at a normal idle.
2) Connect a Voltmeter Directly Across the battery Terminals.
3) Turn on Headlights to High Beam.
4) check the battery Voltage.
*** The Battery voltage Should read between about 13.8 to 14.2 volts. (Possibly up to 14.5 Volts.)
5) Increase motor speed to about 1500 RPM. The Alternator should now produce a battery voltage between 14.2 and 14.6
Volts.
*** If it is Lower than 14.2 volts, the Alternator probably has one or more Bad Diodes.
6) Now, Maintain the 1500 RPM and Turn off the Headlights. Run this test for One Full Minute.
"The Battery Voltage should NEVER Exceed about 14.8 Volts".
***If it Does, the Alternators Voltage Regulator is probably Faulty, OVER CHARGING the Battery.

I dunno if its the battery, the car is cranking maybe fuel pump? That has to strong of a crank..... But jumping the car would be my first try, other wise im not a mechanic but sounds like its not getting enough fuel.

Thanks for the input but my battery is fine I don't know what it was but the car started up last night and is starting fine today I was told my a Lexus mechanic maybe my push start button is having issues

Sounds to me like the intake. Did you recently change or do anything to your intake? Check the Mass air sensor, unplug it and plug it back in? I have had similar issues with this and it was all because that sensor was not plugged in all the way.
