Well to start I put a 2002 5.3 and t56 into a 1998 s10 I noticed a slight sound in the passenger side exhaust for a while now but it still seemed to drive alright well I started looking into it more closely and found out the cylinder 8 injector wasn't plugged in so I plugged it in and it ran well and then began my trouble I set out to drive it and very shortly after the whole passenger side quit firing you can unplug the main connection for all the coil packs makes no difference so just to try it I took the number 8 injector back off and idled shortly then the other three cylinders came back to life and will run that way as long as you want when you return the number 8 injector plug it runs on all cylinders shortly then loses all on the passenger side it's weird I'm not sure what's going on any opinions?

I would meter the injectors and see if number 8 meters like the rest of them. Maybe even swap a couple injectors around and see if the problem follows.

Tested the injectors on passenger side the one in question was 14.7 and the rest were 15 range the wires tested at 12.30 on all of them and they all flashed the test light so guessing that number 8 injector is bad

I would still move it to see if the problem moves with it, before shotgunning a injector, unless you have a extra injector. JMO

I had the injector pulse tested when you start the engine both sides are around 5 then the passenger side slowly dives down below 4 then the passenger side of the engine quits and it's at 1.50 .The driver side pulse goes up as the passenger side goes down does this mean something is wrong with the computer?
