I'm getting a p0193 code. And I've already done pump, filter, driver module, and rail sensor. Took it to the dealer and let them run their test plan. They came up with a faulty pcm. So I replaced it too. Didn't fix my issue.

According to my scanner on live data. Pressure is 51psi. I haven't checked it yet with a manual guage. And at the pump I'm getting 5 volts which I assume is ok. But the code reads to little or to much fuel. I'm at wits end here and I have til August 2nd to take it back to the dealer for them to try again. Any help would be awesome.
