i have had my sr20 blacktop for almost 6 months and haven't been able to start it up because it has no spark. I have replaced ECU and wire harness as well as the plugs and it still has no spark. any ideas what could cause this?

Ignitor chip? is the coilpack harness grounded right? there are many things it could be....

i would check the ignitor chip also. check your ground.

I know the ignitor is good but i havent checked my ground

check the orange wire on the dash plug.

Are you running stock ignitor? or Q45? If your not getting ANY spark to any of the spark plugs chances are its not the coils. Check your grounds and CAS.

i would say Cam angle sensor.

set the motor to 0 degrees ( top dead center, but not really ) align the pin thats above the crank pulley to the colored tick on your crank pulley.
take out the cam angle sensor and check to see if the dots align up.

there should be a better explanation of it if you use google.

cam angle sensor has been replaced and still no spark, and its a sr ignitor

Check all grounds on the chassis, who did the wiring on the swap for you, are you sure its done correctly, check your cas, check the ignitor(make sure its getting signal in one side and out the other) check the grounds on the coilpack harness, check the grounds for the block/engine itself(EVERYTHING)
