Classic symptoms of AMM failure. Pull the electrical connector off the AMM then try starting. The ECU will see the missing AMM signal and use "limp home" mode to run the engine. It should start and keep running, albeit rough, especially above ~2000 rpm. Acceleration will be pitiful, but the car is still drivable in an emergency. Avoid removing/re-connecting the AMM with the ignition ON, too much risk of an electrical arc frying electronics.
