IPR at 60psi with engine off?

While trying to diagnose a skip in my powerstroke AE is showing 60psi Injector pressure with the key off and .3 volts I believe. Ran AE on another PSD and it slowly ran down to 0after being shut off. It's a new Injection pressure sensor and harness. Reads about 500psi at idle. No CEL and no codes, if you unplug it it will throw the CEL. Any ideas what may be causing it? I'm pretty sure the ground signal from my PCM isn't working if that ties into the sensor somehow.
