Hey guys. First post here but been lurking for a couple years. I've got a 2019 platinum that I got last year in February with 26k miles. Now at 66k.
Last winter I remember only once or twice when it got really cold, I would get in after a remote start and would see an error on the dash saying "fuel pressure low". But it never left an MIL on, and drove fine. And then just never saw it again. Until a week or 2 ago. Saw it once or twice at random again in the lower temps, and same story. I thought just some water in the fuel.
Well this Christmas weekend my wife and I took it to Tulsa Oklahoma for the holiday, and it started doing it almost every start. Or at minimum half of them. So I realized now I have a real issue and not just a bad batch of fuel or water in fuel. It made the trip fine with me babying it and nervous since it's Christmas weekend and I don't have another vehicle.
Now that I'm back home in Texas, it's still doing it. Even in the 40s and 50s. I ran forscan and see a P008A code in 2 different places. Both thankfully are for the low pressure pump (I'm guessing in tank?). Truck has 66k miles so no power train warranty left to cover it.
I know that if I don't fix this soon, it will eventually kill my HP fuel pump, and God knows I can't afford that. This is our only vehicle at the moment.
I'm plenty savvy to fix whatever I need to. Question is, do you think replacing the low pressure in tank (or wherever it is) fuel pump will solve my issue, or could something else be the culprit?
I've also been monitoring the desired low pressure vs actual low pressure fuel PIDs as well. Desired seems to be around 64.5PSI and actual is around 63 to 64, but since I've been monitoring this, it hasn't given me the low fuel pressure message even once. Go figure now that I'm actually trying to diagnose it.
I run got shots secret EDT year around and change fuel filters about every 20k miles.
Any advice is much appreciated!
