Cranking but no start was created by NiklasH

Hi
I have a jimny -99 that won't start, doesn't get any signals out of the ECU box.
Have measured the input signals that can be measured and they are correct.
Has taken ECU, key and immobilizer from another -99 but it does not send out any signals to ignition, injection or tachometer.
Replaced the cam position sensor and those signals are correctly entered into the ECU.
Have no error codes and have run out of ideas how to continue troubleshooting.

Welcome to the forum

Checked grounding / earth / minus on the ECU?
Fuses?
dashboard cluster, what lights work and wich do not when ignition on?

The dash cluster is wired into the ECU so some grounding in the harness comes from there. Cluster print boards can fail also.

Thanks been here for a while but didn't register me

Have checked all ground and + to the ECU and they are correct.
All fuses are intact
I have changed the dashboard cluster from the working car and it is the same lamp that lights up on both cars
