I have a 2008 Speed 3 that will start and stall after about 15 seconds (or sooner if I step on the gas) if I have my snap on scanner on it and go into "Output controls" I can turn on the fuel pump and the car will run like a scalded dog! if I dont turn it on electronically, I wont get out of my driveway. Low pressure fuel pump runs with scan tool. GDI pump obviously works. I even replaced the "fuel pump resistor module" on the body above the transmission.
