ProEFI and Fuel Pump Question
For anyone with experience on here. Tried a couple shops and haven't really got an answer on my question yet.
I have everything wired in for my ProEFI 128 setup and I can't seem to get ProEFI to turn on my fuel pump(s) when cranking. If I run off of the stock ecu, fuel pressure jumps right to 43.5 once the key is in the on position and starts on the first try. Once I connect the ProEFI though, when I key on it will not start the pump, but everything else comes on fine.
Any thoughts?
For background, the car is a 2006 Corvette with an aftermarket Fore triple fuel system. I have the primary pump running off of the stock wiring harness, then the second and third pumps being ran off of Fore's external controller. This is being signaled by the ProEFI via LSD7 to a automotive relay that goes to the controller.
Was told that since ProEFI is controlling the TB, that I physically change over the fuel pump to being physically connected to the ProEFI. Tried this and still no go.
