Citroen C3 c3 wont start, no power, wipers randomly on despite being off.

To have so many people to have the car there to check and not be able to get to the fault , beggars belief . " possible crank sensor, " should show as a fault code but engine would turn but not fire . Key fob battery wouldn't stop car from starting as you describe . Some " specialist " if he cant find the fault . If immobilizer should show fault code and usually warning light on . Unfortunately not a lot I can do from here , Check battery voltage , battery terminals and cables , check ALL earths , especially from engine / gearbox to body , check wiring at starter .
