Ok the truck started running really bad, rough idle, hard starts, loss of power code P0192. I have also noticed that my fuel pressure reading has been all over the place, 0-17 psi fluctuations, when normally she sits around 16psi all the time.

From some research using the handy search button, I think perhaps it could be Quadzilla gauge related. Problem is I didnt install it and no instructions so I don't know exactly what it takes to take it off.

 

a few other things to add truck will seem to run fine after a couple of starts. Then once I leave the truck for about half an hour its a rough start and rough idle. Smarty tells me P0192 is fuel pressure sensor voltage low. Could I be on the right track assuming this could be quadzilla gauge related?

 

try removing it and see what happens

 

po192 is fuel pressure sensor is bad that item is covered under the cummins 100,000 mile warranty thats what the dealer told me. and read my post below on code po193 what others had said to jump my sensor and if it throws code po192 that my sensor was bad it cost right at $600.00 if you buy it from dealer
