Here's a similar system. In addition to sensing spark, which arrives as a signal on a gray wire from the ignition computer, joined to the fuel harness under the intake manifold, the LH2.2 fuel computer needs power from the red wire and 25A fuse by the battery, and ignition-switched power to turn on the system part of the dual relay (E) named the "main relay" we call the FI relay (instead of the fuel pump relay, which is internal to it).

After making sure power is OK, pull the cover off of the FI relay and be sure the system half is operating, and that manually pushing the other clapper down starts the fuel pumps running.

Mahatma Gandhi, as you know, walked barefoot most of the time, which produced an impressive set of calluses on his feet. He also ate very little, which made him rather frail and with his odd diet, he suffered from bad breath. This made him what? (Oh, man this is so bad, it's good) A super callused fragile mystic hexed by halitosis.
