Vehicle is a 2005 LGT 5MT
I have searched high and low and cannot figure it out. After my car has sat for a few, when I turn the key to start the car, it will not get fuel until I few high pitch chirps or squeals sound behind the drivers side dash(possibly engine compartment). Sounds almost like a quick motor priming or running dry. I have tried to listen while someone else starts it but I can't hear it in the engine compartment. After it has been driven, it starts fine with no chirping. I hear the fuel pump sound and only try to start it after it completes the pressure. Are there additional motors that are failing?
Recently upgraded DW 750cc injectors, Walbro 255 pump, VF52 turbo.
