No crisis here, I'm not having any particular problem with my fuel right now. I'm just playing around with a scan tool I just bought. I was looking around for a few things just to learn where they are. I could not seem to find Fuel Pressure. Is Fuel pressure monitored by the PCM? Or is a gauge on the fuel rail the only way to check Fuel Pressure?

Thanks!

Yes there is for sure... I can read it on my scan tool, my diablosport and my HPTuners

It just occurred to me I did'nt mention my year. My Tahoe is a 2008 with a 5.3. I see yours is a 2014. I'm not sure that makes a difference. I'll keep digging in my scan tool, it's probably there somewhere.

I remember a discussion on here sometime in the past 6 months about someone troubleshooting an engine problem and they couldn't get the fuel pressure PID included with Torque to work on their year. I know it works on my 2012, but apparently on like 07-09 or something it doesn't work and you have to use a mechanical gauge hooked to the fuel rail
