WHAT IS THE ENGINE TIMING ON A ?

1999 Pontiac Transport • 200,000 miles

I'm getting ready to tune-up the van, have my plugs and wires and now I just need to know the timing.

Ignition timing controlled by PCM not adjustable

That is correct, it isn't adjustable. However, if the timing chain has never been replaced, you may want to check it with that many miles.
