Hello, I am the owner of Toyota Yaris I 1.4 D4D 2005 after lifetime and I have a fairly serious problem, I can't start the engine.
I will start from the beginning, I had a bump a week ago, as a result of which I replaced the water cooler and air conditioner, front belt, bumper, headlights. After replacing, I started the engine, everything reveled up, but when I turned it off and started again, after a second it went out. I thought, okay maybe it is venting or something and I fired again, everything was going nice so I went home, there were no problems with it, the engine was running steadily, it was warming up, it was going downhill. However, today I started the engine, drove about 2km and the engine suddenly went out. I tried to fire again but none of these things, the starter spins like crazy, but for China does not want to fire, as if electronics would not let him. The check engine indicator, oiler, low and high temperature indicator appeared - they do not disappear. However, I noticed a strange relationship, when I switch the car airflow to the "1" position, the check engine indicator disappears along with the low and high temperatures, the oil lamp still shines and the meter light dims more - the car still does not start. When I switch the airflow to "2", "3", "MAX" position, the check engine indicator appears, low high temperature, oil is still on, the meter light does not dim - the car still does not start. Of course, there is plenty of oil, I checked on the dipstick.
Is this something with electronics? I checked the ground cable because I know that it had to be screwed on again to the replaced belt, but it is screwed correctly, it adheres well (the belt was preserved with epoxy and acrylic primer - maybe it reduces the negative potential conduction?), The other negative cable is slightly screwed lower under the battery and also looks stable, the wires do not look broken, cut, etc. I have no idea which way to go, I am going to check my friends soon, but the relationship I described above is strange. Do you have any ideas? Have you encountered such a problem?
And what does the installation look like after a bump ??? It's best to attach whatever you read to errors as you can from other systems, not just the engine. Check maybe the fuses, maybe the cable will be stuck somewhere .... and short to ground ...
I sat all day today, I was looking into the airflow, so I removed the glove box, the on-board computer, the whole bacon and, as it turned out, one nest (I don't know what it was responsible for) was mass by default with a metal plate. However, the plate was broken, so there was no mass. I re-drilled the metal plate, put it through the screw and screwed it into the car body - the car starts to touch, everything is fine. Such a triviality ... the best part is that at the beginning I connected the computer under OBD and the program indicated 4 errors associated with the fuel system, i.e. SVC valve, fuel pump, injection and something else. In any case, as if someone had a similar problem with firing - IMPERATIVE CHECK ALL WEIGHTS. Greetings
