First, let me say I'm a tard.
I've always been either unplugging the FICM (LLY) or the individual injectors on the LBZ+.
I tried all the fuses on the LBZ today, and didn't find the "magic bullet" that disables the injectors and permits the engine to be cranked.
Well, DUH...
You have 2 bale connectors on the top center driver's side on all Dmaxes. The top one is mostly sensors, but the bottom one is ... drumroll ...
THE FREAKING INJECTORS! No lower (large) bale plugged in, no injector can fire. Funny thing is, I knew this since for awhile I was datalogging and had mapped all the bale connectors so I could see the injector timing.
Just unplug both (you kind of have to unplug the top to get to the bottom anywho), and you can crank till your battery dies without fueling the engine.
I imagine many folk already know this, but the question keeps popping up, and I'll probably forget again, so here's the Cliff Notes:
To disable the injectors for compression testing, unplug the bale connectors.
