ok my car is dead and wont crank.. i have gas, its not the battery, im getting spark, i replaced the main relay, and today i put a new fuel pump on and i blew 2 fuses while trying to start it. i swapped in a z6 and i still have the old ECU in there (from the d15b).

do you guys think my ECU is fried? and time to get a p28??

 

Try running the right ecu, also check ur wiring harness, make sure you've grounded everything right. When doing a swap once, me and a friend left one ground on the harness disconnected by accident, and when we went to go start the motor, we would be cranking it for what seemed like forever, but never getting it to start and idle. We plugged in the ground, and it started right up.
