Is there a safety mechanism to cut fuel delivery at the regulator, or elsewhere downstream from LPFP, when fuel temperature reaches 200 degrees Fahrenheit? R60 N18 Throwing code "2C03 high pressure fuel plausibility too low" when fuel temperature reaches 200 degrees Fahrenheit. Desired/Requested fuel pressure and rail pressure plummets to less than 100 psi, engine sputters and dies. I've also pulled rear passengers seat and hooked up a test light to LPFP power wire. Test light does not flicker or go out when engine sputters and dies. Nor does the LPFP "electric hum" change pitch. The LPFP stays on until AFTER the engine dies. There's no evidence pointing to the JBE cracked solder issue. Replaced HPFP (Bosch), LPFP relay, LPFP fuse, spark plugs. PLEASE SEE LINKED VIDEO. I'm navigating through my scan tool live streaming relevant data points moments before the issue occurs. I am narrating to help answer a lot of questions you might have

***edit*** Jbe board looks fine.

 

Did you figure out what was wrong? I'm having the same issue
