I was able many time to reproduce the open circuit condition when the original CPS of my XF went defective . This test will confirm the cause of the no start condition or a stall in the trafic when engine get hot egnough.

Yep, he had been on the sales side. I didn't think you could get around that shield from underneath, but it was worth asking.
