Too much fuel--- try cleaning the air filter first if this doesnt work then its a sensor problem and i suggest taking it to the dealer as if your not sure what sensor it is then it can be costly changing a perfectly good sensor .

1988 mercedes 190 e only runs if I dump fuel down the carburator then dies. Its not getting fuel for some reason.

The fuel pump has gone bad in it. It's time to replace it. I'm sure that the carb. is fine since you can dump fuel down it and it will run for a short time. Fuel just isn't getting into the carb. for the car to run right.

Hello my fuel pump pressure, maybe weak, if so how do i fix the problem. I have a 1985 Mercedes-Benz 190D. Please, if someone can give me some advise what to do. Thank You

I just had the same problem with my Chevy S10 Pickup. I changed my fuel pump myself, and that solved the problem. Fuel pumps can range in price, depending on if the sending unit is sold with the pump or without. If it is something you can do yourself, I would recommend it. You will save yourself a lot of money, otherwise look at spending about three to four hundred dollars for a mechanic to do it. It is pretty simple, and you SHOULD buy a mechanics book for your car, which you would find at any auto parts store. You may need to buy a few tools, but that cost is pretty low.
Three years ago, I had a mechanic replace my pump. It cost me 450 dollars, not including the cost of the pump.
I just replaced it again a couple of weeks ago. The pump was $240, tools were $40. So, that is why I would recommend you do it yourself if you need to save money.

Mercedes benz 1992 190E

Lift the hood. Just below the screen, opposite side from battery, you'll see a plastic cover shielding the engine management, abs control box etc. If you search around there after removing the shield/ cover you will find a relay with a fuse plugged into the top of it. This is the pump / system relay.

Oil is mixed with benzin in oil carter

You getting benzin (petrol) into the engine oil??? I'm assuming your 190E is injected? Problem could be your fuel distributor. If you remove the lines from the fuel distributor that go to the injectors. turn on the ignition just so that the fuelpump kicks in (it only stays on a short time to pressurize the system)... there should be NO fuel coming out. If fuel bubbles out of any of the 4 (assuming a 4cyl) lines of the fuel distributor than the fuel distributor is 'faulty' and feeds the injectors to much fuel and the excess fuel washes itself past the rings into the engine sump. This can be caused by one or more of the O-rings inside between the plungerhousing and the upperbody or even some perforation in the gasket membrane.... either way the fuel distributor is not a servicable part, Bosch does not sell any kind of kit for the internal parts as the fueldistributors are factory adjusted to a certain flow and as new parts be of different thickness etc. the flow would be outside manufacturers settings. Cheapest solution would be a secondhand unit.
