found bad injector

Hi I'm new to this forum and new to owning a diesel(7.3.power stroke) I just got this truck a week ago. The po could not get it started so I got a good deal on it(I think)time will tell. The batts were dead and the starter relay was not wired up. With the help of this forum I got it wired and charged the batts. I cranked it over and it tried to start. I could not get it going until I sprayed a little either in it . About 5 revs and it started. I got it home and found out that the gpr was bad(again with the help of this forum). Changed it and it starts every time. That's when I noticed a bad miss in it. Its the #5 injector . Using an ohms meter I checked all of the wires going to #5 and all are good. Put the meter on volts and checked the wire that plugs into the injector itself and started it and it was getting a signal . Is there a way to test the injector while it is still in the head?

How did you determine is was injector #5 again? Do an injector buzz test, that will be a start.

Thanks for the reply
I disconnected the wire going to the injector(#5) while it was running and there was no difference in the engine miss, I also did this to #7 and it did make a difference. I got ahead of myself. I first removed the uvh one at a time. I did all four connectors and the one that controls #5 & #7 was the only one that didn't make a lot of difference(not as much) as the others. then I checked #5 & #7 separately

Ah ok I see. I'd still do an injector buzz test to verify it's bad and give me some more reassurance. But other than that it sounds like you might have nailed it on the head.
