2001 Grand Vitara wont start

If each of the cylinders show similar compression (even given the state of repair of the gauge you're using), it would be safe to assume that the valve sequencing (chain) is functioning properly. I'd still press forward looking for "no spark" problems at this point.

Max, that sounds re assuring so far. How and where should I start to check for no spark, other then what I previously did? Thank You.

I don't know of how much help I can be at this point. There are just too many areas that may be at fault here.

It's beyond the days of pulling off the air cleaner lid via a single wing nut to see if you're getting fuel, or snatching a plug wire to see if there is spark. Computer ports, codes, barely accessible components, intricate wiring bundles, emisions control circuits / sensors and the need for high tech diagnostic equipment has just about forced us to fall prey to the big shops and dealers service bays.
