2017 5.3 Silverado- Fuel pressure

[Marisela Sauceda]

I am looking for the valve where I can check the fuel pressure but cannot find one anywhere. I was able to find the inlet of fuel going into the motor and was thinking I could somehow using an adapter to check the pressure there. Am I simply missing the valve where I can check the pressure or am I suppose to use the inlet?

Those days are over,you need to scan it

Riverbanks beat me to it. Was gonna say, I'm fairly certain these are all GDI (gasoline direct injection) with pressures north of 2k PSI. Scan tool is the only way to see pressure, even in the low pressure side of the system.

Not sure I would ever want to vent the fuel line with pressures over 2kpsi.  Wouldn't surprise me if fuel suddenly venting that pressure would self ignite.

Good point,and there is a whole set of codes for low and high pressure,let's hope they throw the light on when a issue arises, fingers crossed
