Above 60 psi if it is a CPFI= Central Port Fuel Injection. wish I am sure it is, all Vortec engines have this CPFI.
Need to check Fuel pump relay and fuel pump fuse. Also need to check fuel pump pressure. Is there fuel in the tank, Gauge may be lieing to you.
52 psi
no the vortec is computerize and that runs the fuel pump At a greater pressure than be atained by a mechanicle fuel pump.
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.
depends on the type of fuel injection on the motor... on the CSEFI injector assembly the regulator is located under the air intake plenum on the back of the fuel meter body. If it's TBI, the fuel pressure regulator is located inside the throttle body.
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.
65 pounds of feul pressure
It is in the throttle body.
Blown fuel pump fuse, faulty fuel pump, or clogged fuel filter.
