I have a Holley Sniper EFI and was about to do the initial power up to begin the calibration wizard using the Sniper EFI touch screen. But after turning the key to the run position, the LCD touch screen failed to power up, indicating I didn't wire the Sniper EFI properly.

I suspect it was how I wired the switched ignition wire (the pink wire on the Holley Sniper). Looking for some feedback from those with Holley Snipers as to where I screwed up. I'm not using a CD box. My engine is a Blueprint 306.

Here's how I wired mine:

Pink wire - spliced to the light blue EFI crank power wire from the ignition switch

Red wire (battery positive)- Connected to battery positive terminal

Black wire - (battery negative) - Connected to battery negative terminal

Blue wire (fuel pump output +) - Connected to the fuel pump

Yellow wire (coil input -) - Connected to the coil negative input

Dark green wire (crank signal negative) - not used

Violet wire (crank signal positive) - not used

Thanks for the help.
