My Altima ran hot on the interstate and completed shut off. Now the motor will turn but will not start.

Could it be a safety feature that shuts off the engine if it overheats?

I also had a prior head gasket leak but I fixed it with "blue devil", since then after overheating engine its leaked in to the piston heads water. I have cleared all water and still wont start?
Do you

If water is still going inside the cylinders-get it block and pressure tested-she won't start bcuz water is mixing with gas-start here

The sealant was temporary at best and sounds like it has failed.

You will have to remove the head and have it inspected for damage.

Water is not entering the cylinders but still it wont start. The only sound it makes is coming from the starter (and turns), no sound from spark plugs. Im thinking there is no current to spark plugs, ould it be related to a nissan safety shut-off? I have just now removed battery cable to see if it clear's codes?

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
