okay so I have a friend whos prelude died and i m helping him fix it.
No spark
Coil tested good
Igniter tested good
rotor does turn (no not timing belt)
changed main relay and that didnt work
what else could it be?need help asap kinda
could it be the ecu?

 

did you check the battery?

 

i didnt ...idk if my friend guys did before I got there though.but ill double check.it had enought power to turnover the motor so idk.ill double check...any other theories here?

 

check all the fuses also

 

double check and be sure the connection to the dizzy is good. May sound dumb, but I actually did this myself when I did a motor swap. I wasn't getting spark, so when I was unplugging my dizzy, 1 of the plugs just fell out. I push it back in, and the car started right up

 

if you could? i would use someones dizz, cap, rotor, wires, and see if it would start?
honda don't really go bad, but if they do its the Igniter?

 

igniter n coild tested good.my dumb *** totally forgot to check out the msd box that was all the way to the side of the engine bay.but i guess thats where ther problems pointing to.
