the only things needed are spark, fuel, comp, and timing. Since its a COP ign, it's doubtful you have a spark timing issue. So I'm stuck at comp test

Then it may be another factor of incompatibility with your ECU as mentioned in your other thread, unless that's been taken care of since then.

so this is what i came up with my compression is fine but i am coming up with code p0322 which has to do with the speed sensor which makes sense why it wont start. i tested the ground wire and it is getting a good ground so im thinking that somewhere in swap it got damaged right

I dont know which car and code which engine came from because your next to impossible to understand, but I'm assuming the bottom ends are both 06a blocks or else the sensors just wouldnt match up. BUT, as far as I know, all AEB cars use Ignition Control Modules (ICM's), and the newer ones do not. They are both coil on plug setups, but the newer ecu's have ignition control built in. Most likely your problem.
