I got most of my wires all figured out and now the car still wont start. I have checked fuel and it is working. I also checked to see if there is power going to the coils and there is. My only guess is that the ECU is not grounding the coil which is keeping it from signaling a spark in the chamber. I figured this from attempting to ground the spark plug wire to see if I get an arc, and sure enough I didn't.

I am running a S5 T2 swap from japan. I am using the NA harness and the ECU that came with this engine.

Any ideas on whats going on will be greatly appreciated!

Look Directly under the Brake Master Cylinder and you should see a couple or three shielded connectors. Get a spray can of electronics cleaner at the auto parts store, open the shielded connectors and spray thouroughly. Sometimes over time brake fluid gets in the connectors and the one that comes from the CAS (Crank Angle Sensor) is particularly prone to (due to really low voltage in that line) not allowing current through to the ECU. If this is not the problem you only spent $5 and about an hour and it never hurts to clean those anyway

my car does the same thing sometimes. take the egu inj fuse off turn over the engine for ten seconds twice then put fuse back in. try to turn on car it should start. it probably just got flooded. if it continues link that fuse to a cutoff switch and that should solve your problem. if wires are working and car still doesnt start do this
