P1093 and p1094 codes with rail pressure not matching at wot only . Thinking bad pump but replaced pump and now still getting no start unless I spray it , so I know it’s fuel related but hope it’s not injectors cuz I have no sign at all of bad injectors . Hope it’s just a bad pump out of box . What would yall think with the little data I gave ya . P1093-1094 rail pressure 8k and desired at 23 k at wot only , other than that pressure it’s spot on than trucks cuts of sitting there idling . Had to prime filter head to start it . Drove ten minutes cut off at red light . Had to prime the hell out of it even with fass lift pump got it running and dies 20 feet down the road and limped It home . Replaced cp3 . Got no start unless with spray , got the p0089 code and surge at idle but pressures were spot on while driving but now no crank still . Fuel leak at cp3 fittings and somewhere on back of housing . Sent it back , have another pump otw! Help me save some money for diagnostics trying to save money
First, you definitely shouldn't have to prime it with an electric lift pump installed and working. You still have to blead the air, but you should have a few psi at the Schrader valve for fuel near the alternator. This situation is very hands-on for diagnostics. I have seen problems with every part of the fuel system on these trucks. There is a high pressure relief valve on the fuel rail, which can cause this also. But, I'd start with verifying good feed to your cp3 pump. I always suggest looking for an expert in your area. I know they cost more money but you'll save money and time in the long run.
It is the N2 Neuron made by Curien. This has quickly become my favorite meter. Make sure to check out my N2 videos. There is a little learning curve, especially to make good use of the waveform mode.
FOR A SMALL TOWN TECH,,,,,,,,,,,,,,,,, THAT'S A DAM GOOD JOB HOPE TO SEE MORE VIDEOS FROM YOU AND THANKS FOR YOUR TIME
Thank you for your time

What is the graphing tool you are using with your phone. I think you called it a N2. I need more information on it because I would like to get one
