Does your car have difficulty starting or refuses to start at all? There can be many reasons, and one of them, quite common, is a malfunction in the fuel module.
You turned on the ignition, but instead of smooth operation of the engine, you suddenly heard that the starter was idling. Try turning off the ignition and after 40 seconds turn it on again. When turning on, listen to the work of the gas pump. In Kalina, it is submersible and is located inside the gas tank, under the back seat.
If the situation repeats itself, then do not be nervous, do not panic. Start by purging the cylinders. Perhaps before that, your car had already signaled to you about a malfunction and also did not start up the first time, and you, wanting to help it, squeezed the accelerator pedal when starting, which is fraught with a "flood" of candles. In this case, blowing out the cylinders will help you dry out the spark plugs.
If this procedure did not help much, and you literally feel that the car does not have enough "power" to start, then the reason for this may be a problem in the fuel module, which consists of a plastic cup, a cover, a fuel pump, a fuel pump holder, a pressure regulator, two corrugated tubes, mesh filter, float and fuel level sensor.
Often the fault of the fact that the car has difficulty starting or refuses to start at all is a fracture of one of the tubes. Over time, they seem to freeze and microcracks appear on them. Also, over time, there are malfunctions in the FLS, and as it turned out in practice, this part for Lada Kalina is a real deficiency!
And since it is not always possible to immediately determine the cause of the deterioration of the car's performance, the gas pump, in the event of microcracks in the corrugated tubes, has to work in a higher mode, which accelerates its wear.
In this case, it is more advisable to replace the entire fuel module assembly. In addition, in terms of the amount it is not very expensive and you will save your time in search of parts for it.
Opening the hatch under the rear seat gives you access to the module. Disconnect the wiring block by pressing on the spring clips, disconnect the tips of the fuel pipes from the fittings of the fuel module cover one by one, with a screwdriver rest against the protrusion of the pressure ring so that the screwdriver blade simultaneously enters the groove of the fuel tank flange, while the ring rotates slightly counterclockwise. to other protrusions, gradually turn off the ring. This is the most difficult part of replacing the module. Removing the fuel module from the tank, when removing the float, be careful not to break it. Someone's spare parts may be useful to you. We remove the rubber gasket, inspect it for wear and damage.
The installation of a new fuel module is carried out in the reverse order.
When installing the module in the tank, the arrow on the fuel module cover must point to the rear (towards the trunk). Arrows on the fuel module cover fittings indicate the direction of fuel travel.
We put the fuel pipes on the fittings of the module until the spring clips click. Having connected the terminal of the wire to the "negative" terminal of the storage battery, we start the engine and check the tightness of the connections of the fuel pipes.
That's all, enjoy the smooth operation of the engine and the power of your car!
Good luck on your way!
