Since you're using a Terminator I figured I'd share a lesson of the day. ..  ;)
If you have the latest version, at least V3 Holley made a output test mode. The HP and Dominator have this mode to and the same rule applies.
This mode is like using a scan tool for OBD can bus operation of components. It'll allow you to say test the coil or injector driver's from the ECU/Terminator.
Lesson: inside the software you can test the fuel pump but nothing tells you that the Holley circuitry is designed to not fire injectors if the fuel pump relay control circuit (really-pins 85/86) doesn't complete a path to ground as a low trigger input for the injector driver's.
So basically you have to click the box to turn the fuel pump 'on' or no power for the injectors.
I didn't want the draw power the whole time or the possiblity of poring fuel down a cylinder so I pulled the fuse for primary power to keep the fuel pump off. You could pull the relay and put a small resistor as well.

Hopefully you don't have to use this feature but if you do, now you know..but will you remember? :o
