I know it's probably been asked before but is there a way to test start your fbh

I get the click from the fuel pump and that's it
The park heater runs for a couple mins and turns off

I get codes
Park heater interruption and
Flame out on the fbh
If I try priming the pump it fails on code 05
Does this point to the circuit board ?
Where is the temperature sensor as I've heard that can cause the problem too

Any help as always is appreciated
