Clio 182 Crank no start

[SeanB02]

Have a issue with my 182

Got the solid immo light on the dash with crank no start, have checked fuses, white plug, checked power to relays, wire continuity to ECU and backwards all fine.

Had an auto sparky out to it, he said ecu, swapped ecu kit with a known working one and same issue.

This is the faults I got from it.

At a loss now, cant make sense of it.

Fuel evap has always been there same with speed signal, others came with this issue.

Car drove to work fine and then been crank no start since.

Check earths.

Battery to body and earth strap from gearbox to body.

Checked all earths already, all clean and have good readings

Crank position sensor on top of gearbox was an issue for me a couple of times.
Bolts only became the tiniest bit loose and it wouldn't start. Then when engine cooled off it did.

I also had an earth strap issue on another Clio.
