Fuel Pressure

[Coderedsaleen]

I hooked up a fuel pressure gauge and possible having problems. I ran the engine and I have pressure around 38-40lbs which is normal. When I turn the engine off w/key on the pressure bleeds down. When I try and start the engine again it takes a min to restart. So my real question is should the pressure in the fuel rail stay pressurized? :shrug:

Yes and no. I have a return setup and mine does the same.

mine does the same thing i have normall fuel pressure when car is running but if i turn it off and turn it back on it has a hard start. i always turn the key to the on position and let fuel pressure biuld for about 5-10 seconds till my dash lights do there start up check. not an answer just my experience!?
