alright i bought a already done up 240 with the sr swap already done my friend whom i pursched it from said the car was done up right so i bought it ran fine till one day the battery came out of its holder in the trunk and cracked open now it wont crank....now list of things ive replaced to fix such thinking that the wiring was fried i got a hold of a new SR harness and a ka sent it off to be mixed to be sure it was correct (didnt look like much to do but ooo well) pluged it in as well no start.

looked at the ECU thinking that might of been fried sure enough there was a chared spot got a hold of a new ECU pluged that in no crank....

what i do get is a very fast clicking or buzzing from a EGI PUMP relay (yes i did look over all the fuses and replaced that EGI PUMP relay) also there is a buzzing on drivers floor by that cluster yet to track that one down.

now all this happens with the key in the on spot now when fully turned it all stops....cant figure this onw for the life of me...

the buzz in the relay might be a short circuit somewhere. run the wires down and check them.or with a ohm meter check for the short circuit
