On my 2006 I used a fluke to check the wiring harness to the injectors
I tested each pin individually to the ground on the battery and this is what I got.




Also I checked the injectors with the fluke connecting pins 1&2, 3&4, etc.
5 of them were 0.7 ohm or 0.8 ohm
The #5 & #6 pins measured 0.2 ohm

Anyone have any ideas?
The truck starts easy but seems to miss sometimes and blow a little white smoke on start up only, but not all the time. Some mornings its fine. The problem seemed to be worse in the winter, but its still doing it a few times a week. 260,000 miles on it not sure if the injectors have been done but it seems to run great (smarty SO6 on #1 w/ timing)

 

I'm guessing the solenoids on 3 of the injectors are bad since they are reaching a ground?
