You need to check the pulse exiting the ECU then check the wire loom for disconnected/poor connectors.....

If loom is good you should have B+ at the injector and no ground, pulse is via ground/ECU... DO NOT apply raw B+ to injectors....... Philip

Do a noid test on each injector, which will test for the electrical pulse at each injector (the noid light will pulse). You are testing at the injector connector.

And to repeat what Aqua said: do not hotwire the injector to try to test it.

You need to check how you have the timing setup on this.
