Okay, I replaced the factory unit with a 295 unit yesterday. Car fired up fine, drove about half an hour away, did a few pulls during that time and everything was fine. 80psi all the way to redline. Parked for a few hours and then did the same back home. Now, a few hours after that, the car is stuttering and I’m showing only 17psi fuel pressure and a P062A code. If I just turn the car to ‘run’ I get 34psi, sometimes almost 80. As soon as I start it, 17. Any ideas?

Where are you taking the FP Readings?? Have you checked Fuel Flow??

Restricted fuel filters, kinked/obstructed line, bad pump electrical connection, intermittently bad pump(s). New just means "never been uses; doesn't mean they are any good."

HP Tuner datalog. The same one that was showing me 80psi 8 hours ago.

If I disble the DTC in HP Tuners will it stop the test that produces it?

Nevermind. It won't.

Got it figured out. The new pump blew the discharge hose off the basket nipple. I pulled it all back out and put some clamps on the nips (yeah baby). Up and running again. Hopefully I’m done with it.
