My fuel pressure is set at 30lbs when the car is not running. When I start the car it read about 60 lbs. is that normal?
The car runs fine. Djet 2.0 (IMG:style_emoticons/default/beer3.gif) |

Stock pumps are 65 PSI out of the box.
Have you possibly flipped the feed and return lines around? Did you replace the screen in the tank at the fitting? those do get pretty clogged. The Fuel pressure should be at 30 running....much more than that and you are running way to rich. The FI systems on these cars have no compensation so Fuel pressure is a key part of proper tuning.. The injectors just open and close. There is no O2 sensor to give the system any feedback for running to rich...really just the CHT and once it hits a certain running temp its not even part of the equation anymore... rich |
