I have a sudden preheat failure:
When I put ignition on, I get preheat failure few seconds after.
FES shows error P0380, Preheat failure
I tested with FES, setting the fuel heater on, and
What can be the issue here? ECU can give the command, because I can turn it on with FES, but it doesn't want to do it
Thanks

I tested with FES, setting the fuel heater on, and
- I can confirm that the relay is working (I can hear it and I feel it engaging)
- the wire have voltage when relay is on
- the fuel temperature is increasing slightly . It was starting from 4C to 6.2C. If I remove the wiring, it shows -40C
