Starting problemsi

[u/Proud_Boot_3896]

Hi everyone hope someone will have an idea about this but I have a 1.8 tdci 08 for mo deodorant lynx engine and just this morning it was hard to start it's 14°c but frost waring came on and glow plugs went off immediately, same after trying 3 more times only get 1 second of active time from plugs and frost warning. I can hear an audible click from the relay turning on and off the plugs so I checked that seems fine check plugs seems fine, bit stumped any ideas welcome and thanks in advance.
