shorted the injector to ground

I have 89 tbi car and while trying to troubleshoot it I accidently touched one of the injector wires to gnd.
quick spark and now no voltage to injector; the "other"other injector still has power. Both inj fuses are still good. Thoughts?
What did I do?
thank you
mike

If you have no 12V on the injector power wire at the injector connector then the only thing upstream of that is the Inj fuse.
Have you checked the fuse with a DVM ?

no sir,,no check with dvm.
It was hot outside, i just looked at it.
You have provided me with enough info to realize that it HAS
to be the fuse. I was scared it was the ECM.
Thanks
mike
