NNo less then 55 PSI. and no more then 62 PSI. Factory specs. are 55 to 62 PSI.
NEW ANSWER: hey I'm sorry the answer that I just give you is the fuel Pressure for that engine. You should have at least 25 to 30 LBS. after engine is at running temperature- HOT Higher pressure is okay too. This is OIL pressure.

What is the normal fuel pressure reading for a 1999 Mercury Villager?
It should be 30-35 psi with the engine running.
What is the normal oil pressure reading for a jeep 5.2 engine?
Running at operating temperature around 40 psi.
What is the ideal oil pressure reading for a Buick LaSabre with a V6 engine?
There is no ideal pressure. Of course the oil pressure will be higher when the engine is cold. After it is running and at full operating temp, the pressure should read at least 10 lbs while idling. The pressure will be directly related to how many miles are on the engine and the amount of wear. A new engine will have around 40 lbs when hot and running at 2,000 rpms, and around 30 lbs at idle.

What is idling fule pressure for a 1995 s 10 with 4.3 vortec?
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.
What is the reading of oil pressure gauge before engine starts?
Oil pressure shouldn't register at all until the engine starts and builds up pressure.
What should fuel pump pressure be with the engine running?
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.
What is the purpose of the pressure gauge in a car?
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.
What are the fuel pressure specs for a 95 Chevy blazer?
key on engine not running 58-64 psi engine running at idle pressure should drop by 3-10 psi
Purpose of an oil pressure sensor?
The oil pressure sensor sends a reading to the gauge so you can moniter the engine's oil pressure. No oil pressure means the engine is in big trouble.
