The VAZ 2110 fuel pump does not pump. What could be the reasons?
What to do if the VAZ 2110 fuel pump does not pump, how to find the exact cause and how to eliminate it, we will try to answer these and other questions on this page. In general, there are several reasons that the fuel pump does not pump fuel, so you should not immediately run to the store for a new pump and change it. The motor of the electric pump itself fails quite rarely, some instances work for 5-7 years or more. Therefore, a burned-out pump is the last reason that needs attention.
The VAZ 2110 fuel pump does not pump due to two possible reasons, the first is the lack of voltage and the second is the system clogged with dirt. The symptoms of these two causes will be described. Solving the problem with the gas pump is quite realistic on your own, there is no particular need to contact the masters and pay money for it. Let's start discussing the reasons for this negative phenomenon.
Broken relay or blown fuse
If the buzzing of the fuel pump is not heard when you turn the key, then the car will definitely not start. Often the cause may be a failed fuel pump relay or a blown fuse. These are the simplest reasons that are easy to check in a few minutes.
The relay and fuse for the fuel pump are not in the mounting block, but inside the front panel, next to the "brains". To get to these elements, you need to remove the plastic cover in the area of \u200b\u200bthe front passenger's legs. Under it you can find a rectangular chip with several fuses and several relays. According to the electrical equipment diagram, you need to find the relay and fuse that worries us.
Clogged fuel filters
The fuel pump may pump fuel poorly, or not pump it at all due to clogged fuel filters. We are talking about two filters, coarse cleaning (mesh in the glass of the fuel pump) and fine cleaning (located in the rear beam area). It turns out that the electric pump cannot get the right amount of fuel, and in this mode it will quickly fail.
You need to understand that fuel filters require replacement at least once every 30 thousand km. mileage, this is neglected by many. And if you have to refuel gasoline from canisters, then you need to change the filters even more often. If the replacement is very late, then most likely the filters are very clogged. Then the fuel pump can not pump enough pressure to start and normal operation of the engine. As a rule, replacing the filters completely solves the problem.
