Question about Chevrolet C1500
You need an hand gauge to test the fuel pressure regulator.
The fuel pressure regulator sould be placed toward the end of the fuel rail on one side of the injectors
To test it do the following:
Get rid of the fuel pressure in the lines by removing the Fuel Pump fuse and start the engine with fuel pump off. After it stalls, crank it again.Cranking with fuel pump off will release pressure.
Put back the fuse after this.
Connect the Fuel pressure gauge to the side of the pressure regulator, where it gets the fuel in.
Crank the car and check pressure.
I think that at idle, the pressure should be about:
235kPa - 2.4 kg/cm2 - 34 psi.
The data is not exact, it just must be around this values.
If you disconnect the vacuum hose, you will get about:
294 kPa / 3.0 kg/cm2 / 43 psi.
After gthis connect a Hand Vacuum Pump to the pressure regulator and crank the engine. When the vacuum value increases, the fuel pressure must decrease. If this does not happen, then the regulator is faulty and must be replaced.
