Check the connector with a DMM....with the igntion switched on, you should have 12.Xv (battery voltage) from one of the pins.

Also, measure the resistance of the injector across it's 2 terminal pins and compare that to other injectors. (You'll have to unplug the harness completely I think to get to injector #6)

It could be the injector

It could be the connector

It could be the wiring harness

It could be the ECU (Worst case)

Just to be sure, I recommend replacing everything and upgrading to Cosworth ECU, Mil-spec wiring harness, and Bosch Motorsport injectors.
