ej18 wiring diagram from 93 imprezza

[stinky]

Anyone got an electronic copy? I think we chopped out one too many wires from the loom when putting it into my ea81 sedan.

Symptoms:

 

1) Ignition relay not clicking when turn key to 'on'

2) Fuel pump not getting power from ECU

 

 

 

I've got a thick yellow wire from the Ig relay to +ve through a 20A fuse. Test light shows power to at least this point.

 

I've got a wire going to Ignition power, Test light shows this gets power. Traced to wire into ECU and test light lights up there too.

 

I've got another wire going to the Starter +ve. ( can't remember if I tested that, will test tonight ).

 

The engine plugs are all plugged in, the Oil temp isn't, but the 02 sensor is.

 

I'm told this should be enough to start the engine, but it doesn't.

 

 

Any ideas ?

Here's the diagram.

Just double check all your connections against the diagram and you'll get it. I can't imagine trying to strip a harness without a diagram... Good Luck!

Thanks! The colors on this one are a bit different to mine, but it should help. I actually got the relays clicking, I had a wire "yellow / black" which goes into A10 that needed to be on the ignition circuit. I don't even see A10 marked on yours?

 

EFI fuel pump started spraying fuel out all the joins, so I'm off to get better hose/clamps before I go any further.
