#1 injector problem

Ok guys just got done doing head gaskets, egr delete, studs, exhaust, injectors from warren, 62/70 turbo, sct tunes from innovative. got the truck all put together first startup lots of white smoke. Truck has lots of power just lots of smoke. Pulled the codes only one came up with relevant was p0263. So I traded the number One injector and switched it with the one beside it. Same issue same code. Pulled the injector plug off while truck running smoke stoped. Pulled the injector out now, orings are fine there are not two bronze washers just the one. The injector cup looks fine to the naked eye. The heads were deked and pressure tested. Any ideas? I'm lost.

There is abosolutly no smoke with number one unplugged. Could this be wiring or possible injector cup? Any way to ohm test wireing or anything?

If you have bad injector it won't matter which cylinder you install it in it will still be bad.

But if he swapped it and the code didn't move with the injector than it isn't the injector... Could be a wiring or ficm problem.. Maybe you damaged the harness when you were taking everything apart

You are correct. I did not see if the code went to the new cylinder or stayed with #1 cylinder.

I tested the plug with a volt meter and it was real close to the same volts as #3 now I'm not saying at all that this is the correct way to test it. As I have no idea. If I bought the auto Enginuity would a buzz test confirm wiring? Or is there a way to test the wiring?
