[QUOTE="Luis, post: 29804, member: 11795"] Hello again everyone, about 20 days ago I installed a new, original high-pressure fuel pump and everything was fine. Two months prior, I also installed a new fuel tank pump. Now, a day ago, the "reduced power" message appeared. I checked the high-pressure pump and it's working fine without any problems. I connected a scanner and it's giving me a fluctuating fuel pressure reading from 23 to 80 psi, constantly changing without stabilizing. I checked with a pressure gauge on the fuel line and it's doing the same thing, giving the same readings. I disconnected the high-pressure pump regulator and it's still the same, so I ruled out the high-pressure pump and the fuel line sensor. But when I changed the fuel tank pump, I did it from inside the car floor so I wouldn't have to remove the tank, and I cut the hose that connects that pump to the other fuel level gauge so I wouldn't have to remove the other part, and then I reconnected them. My question is, if it comes loose, could that be the problem with the fuel pressure? Could it be someone else? [/QUOTE]
