Yes, the ign. coil packs at the spark plugs. The lack of ECU case ground will not cause this problem, but is needed to shield the ECU from EMI noise.

Nissan has moved away from their old practice of running the ECU's grounding pins straight to the engine block. There is now a longer "chain" of grounds, where the ECU is grounded to the body under the dash and then the engine block is grounded to the body and finally in this case the coil packs are grounded to the front cover.
