To check fuel pressure you need to have or the use of a fuel pressure gauge.
On both the TBI and Vortex engines there is a test port generally located
behind or near the fuel pressure regular inlet . There is a hard line in which the
port is mounted, most often the port has a cap on it ( similar to the valve stem
caps on your tires or the caps on your A/C lines ).
1997 5.7 engine fuel pressure should be 55-60 psi at start up, running psi
should not drop below 50 psi. Generally if the psi readings are below 50 psi
it is an indication of a dirty fuel filter, weak fuel pump. If the psi is good at start up but drops off a lot at engine idle then check the fuel pressure regulator.
In answer to the question --- once the engine is turned off the fuel pressure
should not bleed off -- if it does , replace the fuel pressure regulator.
YES BUT RUN A FUEL PRESSURE REGULATOR. YOU WILL ALSO HAVE TO HOT WIRE THE FUEL PUMP IF IT IS IN THE TANK.
Where is the fuel pressure regulator located on a 1989 chevy silvarado with 5.7 liter engine
The mechanical fuel pump regulates the fuel pressure. This truck is not fuel injected. It has a carburetor.
It's on the passager side inside the engine department
I think the fuel pump is the regulator on fuel injected engines. The FPR is located on the driver's side of the engine, it has a vacuum hose going to it and is held on with a spring clamp similar to AC connector clamp. On most 1996 Chevy Tahoes the fuel pressure regulator is actually inside the intake manifold. You must remove the intake manifold to replace it.
on the 3.1 it is on top right side of engine.
The 1985 Chevrolet S 10 blazer fuel pressure regulator can be found on the top of the engine. The fuel pressure regulator will be near the fuel injector pump.
Where is the fuel pressure regulator located on a 1998 Chevy van
CFI ? The fuel pressure regulator could be leaking.
There is no 2001 S10 with a V4 engine.
Assuming this is a 4.3L engine, the fuel pressure regulator is located under the upper intake manifold. The upper intake manifold must be removed to gain access to the regulator.
Under the upper intake assembly
