04 corolla not starting tried everything I could think of

Start with the basics - air, fuel, and spark at the appropriate time.

Whether the car will start or not with a bad ECU depends on what is wrong with the ECU.

Some vehicles are equipped with safety features such as as a "rollover switch" usually triggered at a specific degree of angle. I'm not sure if the Corolla has such a device, but if it does, there usually is a procedure to reset it or in some systems design require replacement before allowing the vehicle to operate. Some other devices on some vehicles will not allow starting if an air bag deployment has occurred. Ask Ray O if the Corolla has such a system. He would know, check the manual (it might mention it), or the Toyota dealer would know for sure.

Does it have a fuel pump cutoff that needs to be reset, and since you said it rolled over, did the fluids drain out of the battery? Did any wiring pull loose?

Hmm, if the vehicle rolled over on its side or roof, I would be surprised that the OP is trying to start the car without getting the body work repaired. I've never heard of a Toyota with a rollover cutoff switch, but that doesn't mean that there isn't one in the car.

If the car was overturned and there is body damage, then check all of the wiring connections, especially ground points.

The OP stated that the starter is good, does that mean that the engine cranks but will not start or does the engine not turn over?

Worse yet is there oil in the cylinders? ;)

The systems that I have some experience with switch to open the fuel pump circuit. The vehicle will crank over but not fuel will be pumped. I'm guessing that the car is drivable from his post. I've had to drive some cars that should not have been driven just because of circumstances.

Those rollover switches usually have some kind of reset switch in the luggage compartment, but I have never noticed such a switch in a Toyota.
