All Injectors fire at the same time.
Remove the injectors from the intake runners and cycle the key on / off with the injectors harness plugs
disconnected. If #3 cyl is leaking fuel, replace it.
If the Injectors do not leak, re-connect the harness plugs and crank the engine (disconnect the coil wire from
the distributor cap and ground it). All Injectors should pulse.
If #3 looks to be spraying all the time, rather than pulse, replace the #3 injector.
