One wire of each TBI injector should have straight battery voltage when the ignition switch is in the run position. The other wire is the ground, provided by the quad drivers in the ECM in response to the computer's calculations. The first thing to establish is if there's battery voltage at the injectors with the switch in "run", and while cranking. Gotta have the fuel pump running while cranking, too.
