Its sequential, all have 12v on red wire none have voltage between terminals and none of the signal wires have continuity to ground. Also With the engine running I back probed with my powered test light and saw each injector switching as well as heard each clicking with a stethoscope. Checked for vacuum leaks via smoke through booster line and found none. Hooked up scanner koer test shows both banks rich, but in live data short term fuel is pegged at 25 on bank 1 and bank 2 reads about -17 while long term fuel reads -6 for both. Both o2 sensors are new and I tried swapping them with no change. Also took the truck for a spin and it runs well has power, and even started without too much trouble warm today, well most of the time at least. But the idle is shakey and just revving the motor there is a miss all the way up to about 3500rpm hooked up the vacuum gauge and it read about 17hg, weird though sometimes the idle smoothest out and it reads a normal 19-20hg.. the only other code that is stored is canister purge valve malfunction but there is no cel. And I removed the solenoid and capped the pcv valve awhile ago. I did verify 12v and continuity of signal wire to the ecm and the valve is functional when 12v is applied to it, so not sure what's going on there either.
