Fuel Pressure Gauge Losing Pressure

[Ca_Silvia]

After driving my car when i turn it off my fuel pressure gauge reads 20psi but after it is parked for a while it reads 0psi. Does this mean i have a fuel leak somewhere possibly a leaky injector?

Mine does the same thing.....not sure if it's normal, but I do know on my '95 Maxima I can not crank it for a week or so, then pull the fuel filter hose, and it will spray fuel for a good 5 secs or more

You're not losing pressure! It's supposed to do that. And 20 psi is a bit low for fuel pressure. It should be more like 35-38psi@idle. Check again to make sure your fuel pressure is higher than the 20psi you claim.
