Testing Fuel Pump Functionality on Laguna 3, 2.0 dci, 150 HP, 2013 - Step by Step Guide

Question

Good evening, Laguna 3, 2.0 dci, 150 HP, 2013 - the fuel pump harness plug has 1 of 4 pins burned, which is probably the reason the pump is not working. The car turns but does not start - no computer errors. I would like to exclude the failure of the pump itself by connecting it directly to the...

Thicker cables are pump, 1-mass, 2-plus.

Yes no Yes not necessarily

I apologize in advance for being naive but I am a layman 1. that is, how do I connect the battery to the No. 2 pin and ground to the No. 1 pin, should I hear the pump working? 2. Do I need to connect the remaining pins to start the pump? 3. Will connecting the battery itself start the pump or do I have to turn it off with the starter? 4. Does burning the plug pin result in burning the fuse and if so where to look for it? this is what it looks like in the original

Hello, yesterday I discovered a similar problem at home, but I was able to fix it in an ad hoc situation, I was poking around the fuses, etc. but it was not necessary that the just burnt out contact did not conduct voltage ... about a new cube.
The relay is located in the engine compartment in the box behind the air filter.
but I think first check if you have current on the ankle as I did it with the meter pulled minus with a thin cable and to pin 2 that is next to burnt I gave plus then, it lit up and everything was clear but I cluttered when turning the engine because then the pump should work. if so it will clean the contacts and it should be ok

tomaszi44 · Answer

The car went to an electrician - it was enough to replace the pin in the ankle and preventively replace it
new occasionally acquired pump.
All the fun cost me 350 PLN (150 pump + PLN 200 labor)
For comparison, the estimated repair costs at Renault:
- pump PLN 1,400
- bundle with a cube PLN 350
- labor PLN 350
----------------------
Together 2100 zł

Thank you very much for all your help.

How to open the second lid above the pump itself?

milejow · Answer

The ring nut is unscrewed

pawol · Answer

Nooo, the point is that under the main flap, after opening, there is a second flap through which the cable goes somewhere lower - probably to the right pump

milejow · Answer

The entire pump basket is removed from the reservoir and split open

pawol · Answer

We don't understand each other
I only need to get to the plug on the pump without removing it. Above this plug I have two black lids. The first one comes down with two latches. A second lid with a cable gland appears underneath it. The second lid rests on the metal floor on the gasket. I can't take it off and I mean it. Only beneath it I will find the pump nut and the plug
