ECL not coming on when starting

[CKfour]

Good day tuners, searched but could not find any info on my situation which is as follows.

On occasions when starting my ECL does not come on, and the car does not start.

If i disconnect my battery and reconnect the ECL comes on and the car starts as normal.

The car is a CK4 with a transplanted 4G15.

Any suggestions would b welcome.

Sounds like a wiring problem, have an electrician recheck wiring from harness to brainbox.

Thanks for the reply.

Just got back from the electrician, apparently it was a bad relay.

Just bought a new one and plugged it in, simple as that.

Spotted a new challenge though.

The diagnostic machine was reading my coolant temp. at 199.4 degrees fahrenheit. This was at idle, when revved it would drop down an quickly go back up.

Electrician says its most likely a wiring problem, if you guys have any wiring diagrams it would be appreciated if you can send them to me.

Thanks in advance.
