D4D problem with glow plugs

[Eero]

Hello

I cannot figure it out myself so maybe someone can help me. Car is avensis t22 d4d.I noticed when I turn the ignition, sometimes the spark plug relay did not work and indicator on the dashboard also showed, that glow plugs didnt work. This problem increased and when the relay didnt work, the starter also failed, so no cranking. Last week I tried to turnbthe ignition on and off like I always did, but nothing. I changed the glow plugs, tested and new ones worked, old ones were all dead. But the relay still not connecting them, when I turn the key. No light indicator on the dashboard, no click from the relay. Faulty relay? Faulty coolant temp sensor? And is it normal that starter wont work when the glow plugs wont do their job?

Thanks in advance and sorry for my english.

The starter should be a separate problem, I would think. Definitely test the relay, it could be intermittently faulty.
