well i got the obd2 plug wired up today so hopefully i can get it fixed this week. I checked the fuel pressure today and the gauge was pegged out over 100 psi on the rail. Is this normal? I have a 2002 vette filter and walbro 255 inline with the returnless rails. I just put 12 volts to the pump. Im gonna wire in a relay and wire it to the ecm tomorrow.
