2012 Silverado 1500 4X4

Trying to do a voltage drop test.
What is the best way to turn over starter without running engine? No fuel pump fuse and no relay

In the underhood fuse block there are fuses “INJ-A” and INJ-B” both are 20A. These supply power to all the injectors and ignition coils, so pulling them will allow you to crank the engine without starting.
