LBZ Scan

[Dashman]

I was scanning a friend's truck and I couldn't log Desired Fuel Pressure, Fuel Rail Pressure, nor Throttle Position. Has anyone ever experienced something like this? The sensors or PIDS were inserted into Table Display, and a Chart configured with the sensor or PID. The truck was licensed, and connected. I have a feeling that it's a wiring, sensor, or ECM issue. His problems developed when under load it would go into limp mode. One key cycle and a couple of minutes, and it's good to go again. He says he performed the Bottle Test, but it didn't leak any fuel.

I couldn't log desired vs actual rail pressure, injector balance rate, or any of the other normal fuel system diagnostic parameters on my LB7 either. It's not just you!

That's odd. I can log all of those PIDs with my LBZ. The only thing I can't see, that I wish we could, (which drives me nuts) is injector pulse width. Other than that, everything is there.
