Car won't start when cold but fine when it's warmed up,
we've had the temperature sensor changed but still does it the car itself says it's at running temperature no matter what the temperature actually is any advice?

Is it turning over fast enough when cranking ? does that year model also have a CHT sensor ? ( cyl. head temp sensor ) , Checked / replaced basics like plugs ? Checked cyl compressions .?

Only some models / engines have it and it usually sits between the middle spark plugs on cyl head .

Yeah, that's been changed, but it still won't start cold

Is there not another temp sensor in thermostat housing perhaps ?

What I have found on some sensors that were giving wrong readings after being replaced as that the sensor was not getting in contact with coolant and needed cleaning out with a wire to clear rust blockage until water flowed . Also threads in hole needed cleaned to allow contact with sensor .

I've done that, it sounds like it's not getting enough fuel whist trying to start but once it starts it'll start again until the next day
