01 Lesabre - Correct fuel pressure

What should the correct pressure be when the ignition is on and the engine is off and when the engine is running?

Thanks

Re: 01 Lesabre - Correct fuel pressure

It should be 48-55 PSI... Generally the high side of this with the key on...

with the engine idling 45-50 would be the general area... With the Fuel pressure regulator vac line disconnected 50-60 Psi would be the realm...
