How long should my car hold fuel pressure with key off?How much press. drop if any mpfi.
Depends entirely on the integrity of your fuel system,if you have any leaks (sticky injectors,crud in the pressure regulator.etc) then it will not hold pressure....If you have a good system,half an hour is not unusual....but not needed..
