sorry to bring up old thread, i'm chasing the same thing.. i thought i had a fuel injector leak because on cold start only i would see the fuel pump pressure start at 6.9 and over a period of 5 minutes drop to 5.9... but after the car has been running and warmed up and i do a stop and then start again, it'll hold 6.9 and actually increase to 7.2.
with that i assumed my check valve was okay and it was thermal related so i concluded it was my injectors. however after replacing my injectors its still doing the same thing... so i'm thinking its check valve now? were you successful with your check valve replacement? thanks
