It doesn't have a test port. You have to fabricate fittings to tap into the fuel line at the fuel filter to connect a fuel pressure gauge. They probably sell a kit to do that but I made my own.
Probably a faulty fuel pump.
probably no because Chevy changed the type of fuel injection and it probably operates at a different pressure.
60 to 66 psi.
It is most likely on the fuel pump
Fuel pressure test.
The mechanical fuel pump regulates the fuel pressure. This truck is not fuel injected. It has a carburetor.
41 to 47 psi.
It is in the throttle body.
60 to 66 psi
