The weird thing is that after this test the engine fired at first crank. (7 hours since stop) Engine temp was around 28 c so CSV was activated for sure.
Next is to check sensor plate alignment, just to confirm it's within spec.
Waiting for your comments.

George,
When the problem exists randomly, it would be challenging to diagnose the culprit/s. Double check the setting of the sensor plate before we go crazy looking for unknown culprit. It would be a challenge to align the sensor plate with the AFM (air flow meter) installed in the car. I always do it on the bench but you could do it with more patience.
If I were doing the troubleshooting, I would test for:
- Unmetered air going into the system. Test and verify.
- Residual fuel pressure.
After you have confirmed the setting of the sensor plate, test run the motor and run it for a few mins. and let it cool down. Wait 7 hours more or less and try to re-start the motor. Do not try to start after two (2) unsuccessful attempts. If it starts after a couple of attempts, we’re in trouble.
If the motor failed to start after a couple of attempts, try this:
- Pull out the FP relay.
- Bridge terminals #87A & 30 to test run the FP.
- Allow the FP to run a few seconds to “pressurized” the system.
- Install back the FP relay and try to start the motor.
Keep us posted. Thanks.
Tony
