Blown fuel pump fuse, faulty fuel pump, or clogged fuel filter.
no the vortec is computerize and that runs the fuel pump At a greater pressure than be atained by a mechanicle fuel pump.
52 psi
gmc sierra 1996 feul pressure test
That is were the fuel injectors are at, and the fuel pressure regulator is on the rear of it.
A fuel rail pressure regulator could cause trouble.
Check the pressure regulator, fuel filter and fuel pump.
60 to 66 psi
No, the vortec will be about 60 psi. The 1990 throttle body system will be about 15 psi.
A bad fuel pressure regulator or a clog in the fuel return line that leads back to the tank will cause this.
Above 60 psi if it is a CPFI= Central Port Fuel Injection. wish I am sure it is, all Vortec engines have this CPFI.
It is in the throttle body.
The fuel pressure for a 1.6-liter Vortec engine typically ranges between 55 to 62 psi (pounds per square inch) when the engine is running. It's important to check the specifications for your specific vehicle model, as variations may exist. If the fuel pressure is outside this range, it could indicate issues with the fuel pump, filter, or pressure regulator. Always refer to the manufacturer's service manual for precise information.
