2005 Chrysler 300c 5.7 injector 1 circuit open

I have a code for injector #1 circuit open.
Currently there is white smoke out exhaust witch is raw fuel not headgasket. I put a noid light on #1 and it stay lit on I put it on the rest and as they should they flicker. Idk if this works but I put a multimeter on both ends of injector wiring not on injector itself, and I have my multimeter on ohms with the sound on when I put the wires in plug it beeps does that mean that I have a short woth those 2 wires because it’s making contact.???? Please lmk before I undo harness to find the short.
