Thank you Scott, I appreciate you hunting down solutions.
This is my poor truck. Left today to go to Ennis and hit the drag strip tonight to run slicks (thanks to Everett) and see how far we could push the ol' girl. Changed fluids in all of the drive train, loaded up and stopped to grab a bite to eat. Remembered the gopro at the house, turned back around and as soon as I crossed the road I heard a knock. Realized it was an injector and drove it back the 1-1.5 mile trip to the house. Pulled the injector, removed the tip, cleaned it and still knocking. Pulled it again, assembled it with my tip and a spare injector here at the house and then I couldn't get it to fire.
Went and bought a new injector, swapped tips and stabbed it to make sure (even though the truck should run on 7 injectors) but it just turns over.
Here comes the strange stuff. The actual rail psi is reading a constant 17.9k, and if you unplug the sensor it reads 29k.
Of course, I had to wiggle the injector on the passenger side as I changed the injectors out. So I wiggled them again looking to see if the rail psi on the scan tool changed, nothing... Pulled the plug off the sensor, 2 of the 3 wires are reading right at 5 volts (which is correct for input).
Can anyone verify the volts on the wires of the FPS?
harness has sense been unplugged and reconnected to see if maybe there was an issue at the ECM and the other 2 connectors over the driver side valve cover. No luck.
I have spare LBZ a couple hours away that I bought for parts, I will grab the FPS and whatever else yall can think of that may help.
I hate electrical issues! I could completely understand if something mechanical failed, thanks to JoshH and the tunes the truck gets driven like it's stolen everyday :woott: This issue is just frustrating!
I'm missing the races in Ennis!! horrible!!!!!
