Ken, thanks for the detailed write up and pics. I've got a FAST EZ EFI and Aeromotive Phantom Stealth fuel pump still in the box that I'll be returning.
I have a question about the wiring: all the EFI mfgs require hot electrical source in both On/Run and Crank positions. When I talked to the FAST tech last month he said just that split second in between is enough to disrupt the ECU. Yesterday when I asked the FiTech tech the same question he said it wasn't going to be an issue. Did you modify your wiring at the ignition switch? If not, do you notice anything happening to the system during starting?
