trouble codes 543, 95 cobra


got these Key on engine off codes; 212 Loss of ignition diagnostic monitor input to spark output circuit grounded, and 543, fuel pump secondary circuit failure battery to control module,

I have a 95 cobra with the trick flow track heat top end except I have a stage 2 cam. still have 24# injectors. fox tb setup. almost everything is new but it throws these ground wire codes and I have been looking at it for the last year and I have absolutely exhausted my brain with it. I have a new pcm with it too. new O2 sensors... it doesnt run bad, but its not perfect either. please give me any possible ideas you may have for me to check,
Thankyou,
-Matt
