check youre coolant temp while the car is cold and make sure thats ok . also i would hook up a fuel pressure gauge to see if youre fuel pressure drops slowly while the vehicle is cooling off or maybe low fuel pressure while youre trying to start the car. could be the fuel pump or the regulator.
check the oil level to make sure the engine is not seized. try to spin the crank pulley with a ratchet if it spins the motor is not hurt. there is a single pin wire that goes to the stater you have to check it for 12v while you crank the car, if you get the 12v most likely youre starter went bad.
the coolant temp sensor wire could be the root cause. if the connector is open or shorted it throw the ecu into fail safe mode and will cause the car to run extremely rich.
