So, on top of my problem with hp tuners, my truck won't run withou the rail pressure gauge plugged in. I tried unplugging it and plugging to plug the cummins harness straight to the sensor, when I turn the key on it cycles all the relays and fca. Plug just just the harness into the rp sensor harness and it goes back to normal, will even start but idles rough.

I just had dodge reflash the ecm's to try to fix the problem with hp tuners, and the rp gauge was hooked up when they flashed it.

Does anyone have an idea on this? I want to get rid of my gauges and just use and edge insight...plus I don't want my truck to shut down if the rp gauge ****s the bed.

Thanks,
Chris
