Fuel problems/electrical.

[Alex Rivas]

Got a 2017 Chevy silverado 1500 with the 4.3. Got it about a month or so ago with 95K on it. Shortly after owning it I took it to a car wash and it through a check engine light and had an engine reduced power. So I turn it off for like 30 seconds and it goes away and get it scanned and it has a low fuel pressure regulator light on and this ended up happening twice which had me thinking it was electrical and every time I get it cleared and it doesn’t happen again truck runs fine. Well recently got a new code P2635 while driving and states fuel pump flow performance. Not sure if it’s electrical or the pump going out. Any thoughts? This last code cleared but came back. So I have a problem now.
