Changed looms due to my one being split.

I unplugged ecu and loads water come out. Dried it out and. All looks fine inside.


I have no ecu light on with ignition lights.

In really bad with wires, so any ideas?

At moment car doesn't start

Black ignition live not wired in?

Or fuel pump relay will cause the same issue.

No that's red, permanent live.

There should be a thin black switched live from the loom that you need to wire in.

Yep, two wires going into the reverse switch. Told one is ignition live.

Looks like no pvs for me, since I'm
Working all week and away weekends before pvs. It may be dead ecu as wet. None to test, skint to buy

I'd say your ecu is dead. When mine got wet(c20let) I had no ecu light.

Try getting the ecu apart and soaking it in Wynns electrical contact cleaner for 24hours then try it again. Worked on mine mate

Thanks fazza. I just come to this thread to
Update.

I changed fuel pump relay an thT brought the ECU light back on dash and cAR fired up fine

The relay controls power to ecu and quite a few other things too!
