Hello, I'm new in this forum. I have a 2014 GMC Sierra SLT 6.2L that suddenly stooped running while driving home. I jump started it and I was able to get it started for seconds so I thought it was a dead battery. Got a new battery and same thing happened. Got code P018B- Fuel Pressure Sensor Performance B Circuit so I'm wondering where exactly this sensor is located at, and if possible part number/picture.
Thank you for reading!
