I had it set up that way initially with the (+) and (-) voltages from injector number one. The system activated in the pre-crank position with this configuration. I then changed the (+) input to the computers ignition 12 volt supply after seeing it set up that way in a few of the wiring diagrams on this forum. In this configuration the system again activated in the pre-crank position once before it stopped working. Now all that happens is what you see in the photos.
