Car stalls while driving and will not start again. No codes thrown. Found relay K96 on Junction Box Electronics module to have cracked through-hole solder joints resulting in bad continuity. Relay K96 supplies power to the low pressure fuel pump in the tank, thus with bad continuity, the pump gets no power. Relay K96 P/N is NEC Philippines P/N EP2F-B3G1ST. This issue has happened to many other people with the same car that I know. I suspect heat cycles over time stressed and fatigued the solder joints, causing the joint to crack. Overall the circuit board layout needs a heat sink for the relay to alleviate the heat produced from operation. I am IPC certified and work with aircraft engine electronics regularly and have seen similar issues.
