Will not start turns over and sounds like it is going to start but won't did this last week and then just started.

I do not know year, mileage.Tune up,coils, wires.I had problem for last three mouths ,last night found the problem,change spark plugs,fuel filter,change coils and module still problem,Bad wire #3,now is fine.

usually this is a cam position sensor I have found this problem many times by replaceing the camshaft position sensor I believe this will solve your problem if this is helpful please leave good feedback

If it is a 3.8 engine change the crank sensor,they go bad on the 3.8 engines.

If it won't start have a compression test done and see if one bank doesn't have compression . The intake cam is known for breaking at the front lobe

Sounds like you are having a problem with the starting motor. When activated, it throws out a gear to engage with the flywheel on the end of the engine. If there is not enough energy to fully engage the gear, or the gear does not engage properly due to misalignment, you may hear a grinding noise. Have the starting motor serviced or replaced.

sounds like it was not wired properly-try running a wire from the positive side of the battery to the positive side of the coil, see if it runs-if so, you need to look at how the ignition switch was hooked up.

Sound like a trans sensor but my second guess would be you relay

If car wont start and clicking sound is heard this is a battery related or starter related, if your car battery is in good condition (which I think it was) then the problem is your starter, have it check to confirm.

This could the problem with battery getting drain even if your car is parked , this could the problem in the wiring or the grounding in the car ,first check if any lights or the cd player has the power even if the car is parked ............................

Good luck...

If it turns over but just won't fire and the timing sounds fine when it does run you might consider your ignition switch.  Does it sound like it wants to fire but only just when you let go of the key?
