I am short wiring the car. It now starts and stops straight away. If I detach the battery it will restart but it doesn't run and will not start again unless detach battery and then it will.
I am trying to find which wire I have not attached.
This is not a road car.

Good morning,

I attached the connector view as well as the wiring diagram of the ECM.

Hi Roy thanks for your reply. It is the 22 pin part I am looking at.
Do you know in order to run engine with as little as possible wiring which of the 22 are necessary and which are positive and which are negative looking at wiring from plug to ECU.
The first image is of a different model?

You need to look through the pin chart and anything engine or fuel related is mandatory. Accessories such as AC are things you can not use.
