Hi!!

The fuel system pressure for your Jimmy is 55-61 PSI (Pounds per Square Inch)

Vent the fuel tank vapors by loosening the fuel cap. Position the ignition switch and the A/C system in theoff position. Install a fuel pressure gauge to the vehicles fuel pressure valve. Confirm that no leaks are present, and with the key ON, engine OFF verify the PSI reading on the gauge.

Not sure what you want here, the fuel pressure is in the fuel lines,
the regulator is inside the manifold behind the fuel injector spyder assembly, (not the problem) the fuel pressure test port is on the drivers side manifold cover with a green or grey cap

SOURCE: 2000 gmc jimmy wont start fuel pump comes on and cuts off...

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

Will turn over but it wont start


What is the fuel pressure? these trucks need a certain amount of pressure to start, if low just 3psi it will not start, if you are sure the pump is good then you may bad spider injector. check fuel pressure first and also try spraying starting fluid into throttle body and see if truck starts. the pump needs 60 -66 psi to start the truck.
