If the fuse is on because of the fuel pump - logbook for UAZ Patriot 2012 on DRIVE2
There was a period when I drove with a bunch of 20A fuses:
And I even bought a reusable fuse:
And all because there was a “short guy” hiding somewhere, who did not allow himself to be discovered quickly. The tricky part is that when this fuse burns out, the ECU and some other small things are cut off. The car stalls. And it’s good if it’s not a mountain serpentine, a busy intersection or a railway crossing (everyone can add to the list of unpleasant moments themselves). In general, you need to sort out:
We feel/move/bend the wires going from the fuse box under the hood, through the interior to the fuel pump. At the same time, we observe the readings of the multimeter (it is in the position of measuring resistance), which is connected to the fuel pump connector and the body. Probing the braid of wires in the area of the driver’s right leg revived the readings of the device, which means that somewhere here the fuel pump power wire has a short to the body:
Full size
Here the wires are already insulated and fenced off from the sharp edge of the body, against which they rubbed
After this, the problem went away, but the residue remained. Most of the time I drive on gas, and a gas pump going off while driving will not cause the car to stall. But this is only provided that the fuel pump “hangs” on its own fuse, and not on the one shared with the ECU.
And then, if the brown wire that powers the fuel pump shorts to the body, the additional 10A fuse should blow first.
Realization of plans. To do this you will need the following connectors:
Under the hood in the fuse box we are interested in this red wire (shown by a green arrow), which goes to the fuel pump relay:
We move it to a new location - this is the connector for the additional fuse:
This is how it turned out (top view):
Maybe this approach will give someone an idea on how to implement their own anti-theft system.

Why doesn't the fuel pump deliver gasoline?
One of the most important elements of the fuel injection system of a gasoline engine is the electric fuel pump, which is located in the fuel tank of the car. The fuel pump pumps fuel into the system from the gas tank, creating a certain pressure.
Auto repair experts identify the following common fuel system problems that are related to the fuel pump:
- The fuel pump pumps poorly and does not create the required pressure;
- the fuel pump does not pump when the ignition is turned on;
Considering that the fuel pump is an electromechanical device, the most common fuel pump malfunctions are related to both the mechanical and electrical parts. Next, we will look at what signs indicate a breakdown of the fuel pump and why the fuel pump stops pumping partially or completely.
Signs of fuel pump malfunctions
The main symptoms of fuel pump failure, as well as malfunctions in its operation, are:
- the car starts with difficulty, the engine runs unstable, there are dips, jerking when pressing the gas pedal, etc.;
- the pump does not pump after turning on the ignition, does not turn the starter and does not pump the fuel pump, the engine does not start;
There have also been cases when the fuel pump stops pumping while driving. In such a situation, the engine begins to malfunction and stalls immediately after the remaining gasoline in the fuel line is used up. The problem can occur either regularly or periodically.
The fuel pump does not pump: causes and diagnostics
Let's start with the fact that if the gas tank is full, the battery is charged, the spark plugs are dry and there is a spark, the starter turns the engine normally, but the engine does not seize, then you should pay attention to the gas pump. A common problem is that there is no power to the fuel pump after the ignition is turned on. In a similar way, the malfunction manifests itself in motion, when the power to the fuel pump is lost and the engine suddenly stalls.
An equally important point is how much the fuel pump pumps. In other words, the pump may hum and buzz (power is being supplied), but not create the required pressure in the fuel line. The pressure in the fuel system with a working fuel pump must be more than 3 bar (which depends on the specific car model). The indicated pressure is accumulated in the fuel rail and has an indicator of 300 kPa and above.
To check, you need to measure the pressure in the fuel rail with a pressure gauge, taking into account the indicators that are the norm for a specific car model. Using the example of injection VAZs, the pressure when the ignition is turned on is 3 atmospheres, at idle the figure is 2.5 atmospheres, when you press the gas 2.5-3 atmospheres. This method will help you accurately determine:
- malfunction of the fuel pressure regulator in the rail;
- breakdown of the fuel pump or a noticeable decrease in its performance due to wear;
- severe contamination of filters (fuel filter and/or fuel pump mesh);
In the second case, when you press the gas, the pressure does not increase; in the latter case, the pressure gauge needle rises, but very slowly or jerkily.
A decrease in pressure below the norm will lead to the fact that the engine may not start or start with difficulty, stall, jerk, operate unstably and with failures. If this happens due to the fault of the pump and not the fuel filter, then there is a high probability that the coarse filter screen of the fuel pump is clogged. In this case, there is no need to change the fuel pump itself, since it will be enough to replace or even clean the mesh.

Replacing a damaged electrical fuse
Due to the complex system used in the machine, accessing them will require a certain sequence of actions.
- Disconnect power from the battery.
- Open the cover of the mounting block.
- Find the required fuse and unscrew it from the panel.
- Next, you will need to remove the insert from the seat and replace it with a working one.
With fuses mounted separately, everything is much simpler. Here you will need to find the element and change it according to the standard scheme.
Diagnostic connector UAZ Patriot
Until 2012, the diagnostic connector was located in the center of the panel
after 2011, the diagnostic connector moved to the interior fuse box
Purpose
On the UAZ Patriot, the fuses are designed in such a way that if an overload occurs, a special fuse inside them burns out. Because of this, the circuit opens, but the wiring and all Patriot consumers remain safe. If the fuse blows, then you lose access to a certain car option (the heater will stop working, for example). Without them, the entire electrical system of the UAZ Patriot will be at risk.
In addition, the presence of fuses in the UAZ Patriot allows you to divide the vehicle’s electrical circuits into power and control circuits. Also, inside the Patriot’s fuse box there are relays that close or open sections of the UAZ’s electrical circuit. Therefore, if something breaks on your UAZ Patriot, the first thing you need to do is check the serviceability of the corresponding fuse or relay.
