Help!! starting problem..

[sky88s]

alright guys..

i just finished swapping in a ka24de into my 92 coupe..

heres the problem..

after the swap the car started up and ran fine..

soon after it would idle rough and just die..

so i swapped the ecu and it was idling at 900 no dying problems..i also tuned my throttle..

after i figured that out..i drove it just to find out that it would die out of no where when the RPM drops..

now the cars dead..and im STUCK!!

im asking for some ELECTRICAL ADVICE..

the battery was bad so i got a new optima yellow top just to find out the the starter is also bad..so this afternoon i swapped in a new one..

now when i try to start the car all i hear is a click from the ignotion and nothing else..not even the clicking from the starter..


please help!!!
