2010 Avensis 2.0 d4d t4 sometimes wont start

[Lewis Firth]

Hi sometimes it takes 5 to 10 attempts to start

Is this all the time, or just from cold?

Most obvious one in my experience is the suction control valve fitted to the side of the High pressure pump small valve and get worn out over time and fails to regulate fuel pressure 

 

that said also please check your glow plugs Battery connections starter motor connections and Battery amperage and voltage and injectors too are common on newer t27

Hi

I am sorry to read about your issue, those engines look so complex just to look at. I am sorry that I can’t help.

However we have a 2010 t27 2.0 diesel, and if we drive it at least once in the daytime It fires up the next day perfectly fine, but if we don’t drive or start her up for a day or two, it can take a few chugs to fire up, if left standing for 3, 4, or more days it’s out with the jump starter to make it alive again!!! It never used to be this way, could leave it weeks and she’d still fire up!
 

Admittedly my partner hardly uses this car, but when he does take her for a thrashing, the amount of smoke after the first few minutes...embarrassing to say the least!!!!! He reckons it’s just regenerating due to lack of use!
