Injectors Dilema

[FORMULA7]

1998 Camaro Z28 Auto
Transplanted a 02 ls1 Longlblock in a 98 body.
Ive been trying to figure out some bugs on this car. 2,4,6,8 injectors are not working or should I say opening.Regardless if the injector pigtail is connected or not on the injectors,It won't make a difference.1,3,5,7 seem to be operating and If I remove the injector pigtail on the(driver) side the car stumbles as it should.I tested the power on all pigtails and there is power on them.I traced the side were 2,4,6,8 wires go to the pigtail on the pcm connector with continuity on the voltmeter and there seems to be no broken circuit.Tried two different Pcm's same problem.What gives?Why are the injectors on the passenger side not operating as they should?I'm no tech.Help

You know for a fact its the injectors not firing? You have spark? What PCM (year) are you using? Whats all the other accessory's year's? What injectors?

98 Pcm,28# pound injectors

I have spark,Plugged or unplugged injector plugs make no difference.They have 11.7 volts on the pink wires on the pigtail pins.To me they seem not opening up.

Check the 3 ground wires on the rear of the drivers side head. Maybe reseat both connectors on the ECM. Might have power, but no ground.

Would that effect the injectors?and only the passenger side injectors?

Should have seen my data log when one of my grounds broke off. It killed one bank... I think mine was the drivers side...

yup as Bill said check the ground wires. without a ground the power has nowhere to go
