Last week I got in my truck after it sitting for approx 3 weeks and the check engine light came on. I backed it out the drive and it wouldn't get over 25 mph. After figuring out it was in limp mode, I pulled the codes and began to research them. I'm getting codes P003A-Fuel Rail Pressure Low and P0087-Turbo Vane Position Not Learned. I have found several things to check with these codes individually but didn't find anything with them being together. I immediately thought it was something electrical since the last time I drove the truck, everything was fine. I checked a few things and changed the fuel filter hoping it was that simple but it didn't help.
Tonight I attached my scanner to log a few parameters and see if I could narrow it down to a sensor or see what was going on. The truck does have an edge evolution programmer on it and I'm not sure if that effects anything but when I logged the truck, my Desired Fuel Pressure follows my Throttle Position. I stopped that scan and logged it again, this time my Fuel Pressure follows my Throttle Position. I'll attach the logs. The Regulator Valve Current is all over the place, the MAP is constantly fluctuating, the Speed shows a steady speed even though I'm not moving. The Turbo Vane Position vs. Desired looks pretty good but I'm confused about the other readings. Any ideas?
