I have a 37.3 error code showing it’s disconnected. I tried unbolting and lifting higher but no joy
Some things to try. Give the ring terminal on the ECU earth flylead a good clean with emery cloth. Split the ECU from the heat sink and clean all surfaces with emery cloth. When was the coil/injector/pump relay last changed? Fit a new one.
Thanks Chris, Have had a cold over Xmas, so have been avoiding getting stuck into that pesky battery box. Has to be done though
