Could be a bad coil pack. Just because a coil pack goes bad does not mean it will show up as bad upon reading for codes.

Second thought would be, bad crankshaft position sensor, bad camshaft sensor or both.

Generally, no fire means bad coil pack.

You may look at at a manual. I believe Yukon has two fuel pumps and it might be a possible issue. Another is plugged fuel filter, or faulty fuel pressure regulator.
