I recently purchased a Renault Trafic 2.0dci 2008. The previous owner did not want to light it, and when he did it for a few seconds and then it went out. At the workshop, they replaced him with 2 injectors, but as far as I know, they could not adapt them because the car did not start. So the mechanics said the head gasket.
I bought it like this. To make sure it was a gasket, I unscrewed the injectors and gave compressed air to the holes. Already during the first injection, a fountain appeared in the coolant tank. So it was already known that there were blows on the gasket.
I took the heads off. I have all of them checked together with the rollers. There was a drama after checking out. The head is cracked. "Concave" rollers. As for me, the previous owner had to overheat it nicely.
I bought a new head after regeneration. The head is in its place (without radiator / water) so it's time to check if it fires. At the beginning there was a problem with firing, but it was probably air-blown after a dozen or so attempts, and finally it surprised and there was no problem, the car ran like a raspberry. He smoked to the touch. Satisfied, I finished work for that day.
The next day, when it was dawn, I started folding it to the end. I put on coolers, poured water. I want to smoke, so that the water spreads nicely and that's the problem. The car does not start, and when it catches it, it goes out for a moment. STOP and RED FLOW warning lights and occasional ABS and AIRBAG. I started looking for a fault. At the beginning, the fuel, and it turned out that I do not have the rail or the pump (before). However, after some time, the fuel appeared. However, nothing has changed it goes off and on. I disconnected the injectors one by one and it did nothing.
Is it possible that there is so much air in it? Maybe the injection pump is not working 100%? Is there any sensor that cuts off the fuel supply? Somewhere I read that when the Pillow light appears, it automatically cuts off the fuel, or maybe there is an accident sensor?
I pumped the pear hard as a stone. I changed the fuel filter myself, the filter was ice. I did not replace the sensor with a new one, and I do not know if the one that works. To connect to a computer, I have to take it to the workshop, and for now I ask on the forum. Maybe someone had something similar.
And what about the air intake system - a flow meter
The flow meter was not connected.
Today I checked cables, plugs, etc. It turned out that the voltage regulator was to be replaced. Could it be the reason why I couldn't smoke? As I wrote in the 1st post, without full armament, he smoked a shot, and when, among other things, a PK belt was installed on the alternator, the car did not start. If the regulator did not give the right current to the circuit, the injectors could not open or the injection pump could not deliver fuel to the rail?
Unfortunately, I can not check if it starts after disconnecting the alternator, because the starter refused to obey. Now I am waiting for a new starter and a new voltage regulator
How do you know that the regulator is damaged if you can not fire? Did you check on the "table"? The voltage regulator has nothing to do with ignition. I asked about the flow meter in the sense that the air intake system was assembled (tight) and was the flow meter electrically connected?
There was no need to check the voltage regulator as it fell apart :)
The car still does not start. New injection pump, shaft position sensor also new. I vented it for 3 hours and nothing. Today I unscrewed the cover with rollers and checked if I set everything up correctly and everything is "book-like". What makes me wonder. The fuel from the pump goes, but there's no super pressure there. When I unscrew the cable, there is no oil fountain, only low pressure. However, it does not always leave the rail for injectors. Interestingly, after so many attempts to light the candles, the candles are dry as pepper, and in my opinion they should be flooded.
I disconnected the safety valve, but it had no effect. He burns the cake, the poster will end and go out. I also noticed that the accelerator pedal does not respond to the flame. It should be?
Anyone have any ideas what could be wrong? A slatted strip? Pressure sensor on the strip? Because there's obviously a problem with the fuel.
New injection pump, shaft position sensor also new
You should already come to the conclusion that this car needs to be connected to the computer. Read errors and view a few parameters. You will then see, among other things, what the actual fuel pressure is while shooting. It will definitely be a faster and cheaper repair option. Well, unless you insist and have access to free spare parts, you can change them one by one until you finally hit.

Because you are holding the "gas pedal" in your hand.
I connected to the computer and the mechanic said that according to him, the fuel system is heavily air-permeable. According to the computer, everything is fine except the fuel pressure, but this is the fault of the air in the system and the pump.
Maybe you know any good way to vent? Because what I tried did not work. PS. One of the best mechanics I know.
The car does not start, and when it catches it, it goes out for a moment. STOP indicator lights and RED MILK
In this case, the error in the controller should be 100% saved.

What were the mistakes? What is the fuel pressure while cranking the starter?
Disconnect the plugs from the injectors, run the supply lines and turn the starter you can give a little cake until the fuel appears on the injectors. Tighten the tubes, connect the injectors and fire.
