    Hello
    I have a problem with the fuel pump in the tank. It probably burned up and, unfortunately, it does not burn fuel to the filter, which results in the inability to start the engine. I thought to install a hand pump for now - a pear, but I do not know if it will give the desired effect and the engine will start. I am asking for more informed opinions.

    Rather, you do not inflate fuel so much. This pump is for bleeding.

    Buddy and who installed it there because it's not Renault? There is no pump in the tank in the master, who told you such stupid things?
    Enter the year of the car and how many KM it has.

    Just as a colleague writes, these renault do not have an electric pump in the tank but an initial pump on high pressure and possibly rubber pear. Most likely, you have a leaky system, most often it is aerated around the fuel filter and on the return from the injectors.

    I will not argue because I do not know if there is a pump or not, but the strange thing is that before I turned the key, you could hear something like a pump and you could see on the fuel hose that this fuel flows clearly towards the filter. Now when there is more frost, unfortunately after turning the key does not have this characteristic buzzing and no fuel flows towards the filter which results in the inability to fire. Engine 2.5 dci 115km year 2002

    In what state of the fuel filter?

    Renault Master II generation with a 2.5dci 84kw / 115km engine has a low-pressure pump
    in the fuel tank. Check whether the pump is controlled.

    Hi, I'm linking to the topic, is the control of the fuel pump in the tank via some kind of fuse/relay? Greetings and thanks for any answers

    Before 2003 they had a pump in the tank. Trace the wiring and see if it works, but you'll probably have to remove the tank and replace the pump.

    Whoa, mother and daughter, that's a build up. I'll probably be lying under the master on Sunday instead of under a palm tree in the tropics. Thanks, greetings.

    Have you managed to trace anything? Is there a pump in the tank or a high pressure pump to dump?

Topic summary

The discussion concerns a Renault Master 2.5 dCi (115 hp, year 2002) experiencing fuel delivery failure due to a suspected burned fuel pump in the tank, resulting in no fuel reaching the filter and engine start failure. It is clarified that this model typically has a low-pressure electric fuel pump located in the tank, controlled by a relay or fuse, which should be checked. Some users note that earlier Renault Masters (pre-2003) do have an in-tank pump, while others mention the presence of an initial high-pressure pump and possibly a manual rubber primer pump ("pear"). The problem may also involve air leaks in the fuel system, especially around the fuel filter and injector return lines, causing aeration and fuel delivery issues. The original poster observed a loss of the characteristic fuel pump sound and visible fuel flow in cold conditions, indicating pump or electrical failure. Suggestions include verifying the fuel filter condition, tracing wiring to the pump, checking pump control circuits, and potentially removing the tank to replace the pump. The idea of temporarily using a manual hand pump ("pear") to supply fuel was questioned, as it is primarily intended for bleeding and unlikely to provide sufficient fuel pressure for engine start.
