Help needed 4agze conversion

[MBCorolla]

Hi all, I need some help wiring up my 4agze. It is out of an aw11 mr2 and is going into an ae101 corolla. The engine was running in the mr2 before removing it.

I have kept the body part of the harness for the alternater and starter circuits, and used the mr2 harness for the engine. I have wired the corolla efi and main relays to the mr2 harness and I have power at BATT, +B, +B1 and the earths to the computer are ok. The problem I am having is no spark or injector pulse when cranking. I do get a spark from the coil when the key cycles between "start" and "on" but not while cranking, only when key is released.

Any thoughts what to test next?

Ok I got the car running so here is the info for anyone else. The injector relay was not wired in causing no pulse, and the start wire was not connected to STA causing no spark.
