compression test, fuel pressure test, spark test on that cylinder.
check the injector and wiring. check for vacuum leak around the intake manifold.
when was the last time it had plugs, wires, cap and rotor

What's the engine code / size.
Cap & rotor haven't been used since 1999, so don't worry about trying to find those.
