I still didnt have time to change out the ignition coil, i was wondering where and how do you test the crank positioning sensor, any input. Also i know that if the sensor is broken the car wont start which is what happened to me, but i changed it with a used one, can it cause idle, drivability,hard starting problems?

Testing the CPS is what I posted for you earlier over here:

As for the issue you now have of good cold starts but hard hot starts, leaking injectors would give you those symptoms, but so could failing electrical components, by flexing solder joints, etc. and losing electrical contact as they heat up. The EHA could be an issue, but the EHA is also involved in cold starts, and they seem to be OK, so that's a long shot. I would just do systematic troubleshooting on all of the electrical components, following the FSM diagnostic procedures, and a fuel pressure test too.

I have the opposite, my car has hard cold starts, perfect hot starts, never had an issue with hard starts. Any time its raining, or moisture in the air or cold temperature it takes like 10 long cranks to start, i suspect the EHA what do you think/??
