Good day;

I measure all PCM Voltage, when the engine is hot; cranks slowly and stop; I heck the IAC voltage ( 6.5 - 7.5 ), Coolant Temperature (0, 54-0, 61) ; to start the engine in this condition I have to pull the accelerator pedal, the rpm increase, the voltage up on the diferent Sensors, but I need to wait to stabilize the idle speed; when the temperature sensor voltage is major that 0, 64; the engine craks normaly and start fine.
