    Searching for ECU...

    We have a Factory Five cobra with 427 Blue Print engine with Holley sniper EFI. It's been running awesome for many months but now won't even start. The hand held display for the Holley Sniper keeps saying "searching for ECU". We have tried to update new firmware on the SD card but still says the same. Have checked all connections and fuses. Can the ECU just go bad or should we be looking for something else? Thanks in advance for any help.
