Question about 2000 Chevrolet Astro
When engine is cold, it always starts instantly like it should. Once engine is warmed up, it cranks for 8-10 seconds before starting. while cranking, it doesn't seem to try to start at all for 8 to 10 seconds then it starts. After it starts the idle will drop to 2-3 hundred rpm then right back to about 600 rpm. then it runs fine till next time.
You must RUN the SCANNER/computer for better diagnostic and fix it. YOu can have some faulty like: PCM+BCM+ignition coil, sensor, etc. see the diagram attached.
God bless you

SOURCE: Hard Start with trouble code 32
You should have your battery checked, it may be getting old and doesn;t have as much cold cranking power, I don;t think code 32 has anything to do with the slow cranking when cold.
Trouble Code 32 indicates that the Exhaust Gas Recirculation (EGR) valve diaphragm is not where the ECM expects it to be. The ECM controls the diaphragm with a Pulse-Width Modulated (PWM) waveform. The EGR has a vacuum bleed solenoid that adjusts the vacuum applied to the EGR valve based on this pulse width. If there is sufficient vacuum at the EGR valve, a switch closes to send a signal back to the ECM. The absence of this signal is the bases for code 32.
The conditions for setting this code are:
Typical causes for this code include:
1) Faulty EGR valve-to-ECM connection
2) Plugged EGR passages and/or sticking EGR valve
3) Defective EGR valve
4) Defective ECM

it sounds like you have a injector leaking down into one of your cylinders so it is flooding out a cylinder thus runs rough and long cranks.

SOURCE: rough idle then stalls
Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.
