Question about 2000 GMC Safari
I had the same problem with my 2000 GMC Safari two years ago....drove me CRAZY!
Sometimes it would start right up...other times it just would crank and not start.
It turned out to be a cracked coil....I found it by using a spray bottle with water in it, and "misting" the engine, at night....with the engine running. (On a night when it DID start!)
It took a while, but finally the hairline crack let in some water and the electrical short showed by a spark coming out of the coil.
I replaced the coil with a new one, and it has never "not started" since.
Evidently the coil cover gets brittle and develops small, hairline cracks due to heat from the engine.
Oh...by the way....I tested the coil it showed that it was fine!....but it took the "misting" at night...in the dark...to find the spark "leaking" out.

Look for spark at the spark plugs. If it does not start with starter fluid, may be no spark.
