Over heated now it will not turn over

Check battery for condition including load test if you have another key try that not a new key it may be a bad key setting off anti theft.

Here is a guide that will help

Have you checked to determine if there is both spark and fuel getting to the engine? Simple trick. See if it will start for a few seconds using starting fluid. If it does, there is a fuel problem. If it fails to start, then you have an ignition problem. At least that will help point you in the right direction.

One other thought. Since it has the OBD2 system, if you can get your hands on a scanner, check to see if there is a signal from the crank sensor. That can cause the same issues if it's bad.

Check the fuel pressure to rule out the fuel pressure regulator and the fuel pump. If the fuel system is okay-

Check the mass airflow sensor, idle air control valve and throttle position sensor-

Sounds like the ignition circuit of the ignition switch is gone. What's powering it is the start circuit once you let go-it will die out No power to coil.

another thing to ck is your crank sensor, and I believe its in your front crank pully, since you did all that work in that place of orgin

Fuel pressure must be checked with a gauge 41-47 psi

The first step is to read and record any diagnostic fault codes. Check this page for the procedure:

Check the fresh air tube between the mass air flow sensor and throttle body to be sure there's no leaks or loose hose clamps, and check the vacuum hoses and other signs of a vacuum leak. If there aren't any fault codes, the next step is to connect a scanner so you can view live data. That usually takes an experienced engine performance mechanic to interpret, but you can look at the sensor data to see if anything is obviously wrong.

Hi Hmac300. Didn't mean to butt in to your conversation.

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on.

Just another suggestion
clean throttle plate and body
clean idle air control valve
disconnect battery and reconnect start and let it idle for few minutes and than take it for a ride
hope this help if not done it already
good luck
