34 to 39 psi on 1985-1991 models. The fuel system is under constant pressure (meaning the system pressure must be relieved PRIOR to disconnecting any lines or other parts of the fuel system) therefore, system pressure should change very little, unless there is a leak in the system.
The normal fuel pressure for a 1984 Corvette typically ranges between 36 to 42 psi (pounds per square inch) when the engine is running. It's important to ensure that the fuel pressure regulator is functioning properly to maintain this pressure for optimal engine performance. Checking the fuel pressure with a gauge can help diagnose any fuel delivery issues.
The fuel pressure for a 1995 Corvette should typically be between 43 to 47 psi (pounds per square inch) when the engine is running. If you're measuring pressure with the key in the "on" position but the engine not running, it may read around 43 psi. It's important to ensure that the fuel system is functioning properly to maintain optimal engine performance. Always refer to the vehicle's service manual for specific details and troubleshooting.

You may have broken rings in the 3 dead cylinders allowing compressed air-gas mixture to enter the crankcase.
If the engine is not running the pressure should be 35 to 40 psi. If the engine is running the pressure should be 30 to 45 psi.
Runs continually as long as the engine is running.
Key on Engine not running 55 - 61 psi. Engine running pressure should decrease 3-10 psi.
With key on engine not running pressure should be 9 to 13 psi Engine at idle pressure should decrease by 3 to 10 psi on a throttle body. On a multi port injection key on engine not running pressure should be 41 to 47 psi. Engine running at idle pressure should decrease 3 to 10 psi. Central multiport fuel injection key on not running should be 58 to 64 psi. Engine running at idle pressure should decrease 3 to 10 psi. Central sequential electronic fuel injection key on not running pressure should be 55 to 61 psi. Engine running at idle pressure should decrease 3 to 10 psi.

The fuel pump pressure may vary by vehicle. However, on average the fuel pump pressure with the engine running should be between 4-6 psig.
For the operator to monitor the oil pressure of the engine. If the oil pressure drops below average when running, the engine is in trouble.
The 2013 Chevrolet Corvette has a V8 engine.
