Hi all fellow Toyota owners,
I am new to these forums and I do not want to start my membership with a problem, but it seems that I will
I have a 7th gen toyota celica and 9th gen corolla. And since the cold weather came in last week, the corolla will either start very hard, or wont start at all. It has a D4D 81 kW engine. I changed the spark plugs, starter motor and battery last year and fuel and air filter not so long ago. Also the timing belt was changed by a mechanic a month ago but this is neither here nor there.
The corolla also starts a bit harder than other D4Ds during the summer (or in "+" C weather in general) also, but the real problems appear when temperature drops below 0 C.
The diesel used is also supposedly "winter" grade, from the pump, so that should not be a problem. I also made a video here:
Has anyone had similar experience or has a good advice? I already been in two repair shops and they could not diagnose the problem, because when the car heats up, all problems disappear, it drives well and starts well.
I have read that the SCV valve could cause this, but it also causes loss of power in high RPMs when it breaks, and I have not experienced that. One mechanic suggested changing injectors, but I do not see the connection here also
P.S. I have no troubles starting my Celica in any weather, so I have that going for me, oh well
