No Spark! No Turning over!

Hey guys, I've been over threads and can't find one specific to this issue. Last few days have been very tough trying to diagnose a problem with no luck.
I have put in a new 1.3 Dizzy into the 1.0 car. On startup I get a click at the starter but no turning over. I have "jumped" the car by bridging out the terminals on the starter. it will turn but not get going. I've turned over the engine while checking the sparks and they seem to not be working. I'm aware the immobilizer will affect the spark plugs however with the same ECU and same key I can't see how the new engine would have initiated the immobilizer. Whats the next move here???

Battery is good.
New Starter fitted.
Fuel pressure is up.
No spark.
Dash lights but no engine light when key is turned.
