1994 suzuki sidekick 16v wont start

[fixkick]

once there is spark , the engine runs now on test fuel, even with a dry gas tank.
i can keep it running for 5 minutes on bet. like that.
using only test fuel (instant start in a can), and a key. (a 2 man job)(persons)

when testing spark use new spark plug , gapped to .028" never use old fouled and now shorted plugs to test spark. any spark plug that fits in hand and wire lead works even wrong spark plugs
