proving my point that it doesnt matter temperature the engine is a bad cps will stall with a cold or warm engine. A osilloscope will rule out the CPS.
none of the TSBs for stalling when warm do not mention the CPS. Stalling when warm is caused by rapid pressure drop results in the formation of vapour bubbles in the system. in my case the coolant temp sensor was sending mixed signals to the ke control unit and ezl causing confusion between the ignition and fuel injection
