Question about 1993 Mercedes-Benz Mercedes Benz 300 Class

1 Answer

The engine after starting acts like the throttle is wide open

H2O was added to my fuel tank. (**** hurt Y chromosome) The tank and injectors and the injector pump was all cleaned out however it appears as though the pump was taken apart a little more than it should have been and im now told that thats where the timing is set and it should have not been disassembled. However, damage is done and Im just looking for a solution or directions to re time. its a 1980 300D

  1. whoever opened your pump obviously did not have the necessary knowledge call ''ROVAN DIESEL'' AND ASK FOR HELP. Tell them what you did and ask for help and next time make sure the mechanic you use has a diesel license.

SOURCE: cold start valve problem

if you have an electric cold start valve make sure to unplug it and if keeps apling fuel with electrical conector unpluged that means the valve is not good, but if not then you have an electronic problem, possible a bad cold start sensor or cold start module or cicuit problem, and might be a time to take it to an electrical shop

SOURCE: mercedes E300 turbodiesel, 1999, is poor to start

Yes sir , you have a failing valve, soon it will snap in two....please have your head checked. You can do this yourself by placing a long-handed screwdriver , business end down to each cylinder while pressing your ear to the handle(while engine is running)...you will notice a definite difference when you hit which cylinder has the bad valve. Also makes sure the egr valve is clean and your exhaust recycle valve is not stuck.( located in the crossover pipe)

My car was sugered then I didn't what I first text u fuel pump was good I had it started F awhile then tired if of then stared again it would stared but putter then quit


Hi Delwin, There's only one way to clean a fuel tank and that's to pull it out and pull the fuel pump out of the tank as well because you're going to have to flush both the tank and pump, Also when you've finished reinstalling the tank unhook the fuel line from injectors and turn your ignition on for a minute or two to flush the fuel line, Then replace fuel filter and connect the fuel line back up to injectors........ CHEERS..

did you change the Fuel pump? Most vehicles have the pump mounted in the top of the gas tank. you probably took it out to clean the tank. Sounds like that would be the first thing to check. I would also recommend changing the fuel filter at that time which should be on the drivers side frame rail under the car. Hope this helps!

My 1996 chevy blazer won't start. we changed the the fuel pump, fuel pump filter checked the relay and she turns over once we put gas in the carb. body. help please


Have you ever put in the gasoline tank any injector cleaner yet because the cleaner will unclog the injectors so full amounts of gasoline can get into the piston chambers the right amounts so try putting injector cleaner into your gas tank. When you put this into the gas tank to remember that it takes time for the cleaner to get to the injectors so you might have to keep trying to start the vehicle many times for the cleaner to unclog the injectors. This will not hurt your vehicle at all so go try this.

leaky injector/s is flooding motor, mechanically clean or replace. And clean throttle body while you are at it with spray cleaner. Should be almost spotless where large throttle valve opens and closes.

Rough idleing after pressure wash engine and fuel injector clean


Hi,
I'm assuming you added fuel injector cleaner to your fuel tank rather than using a direct pressure cleaner through your fuel injectors.
When a solvent/cleaner product is added to your fuel tank, carbonaceous deposits (basically the dirt and gunk accumulated over years) are flushed through the fuel system. This can cause major problems if the contaminants manage to enter your fuel pump and make their way past the seals. This can and has damaged good fuel pumps. Downstream of the pump is the fuel filter - once deposits reach the fuel filter, they may block it and reduce fuel flow. The next major problem areas are the injectors themselves (rather sensitive to dirty fuel) and the engine.
Fuel injector cleaner is not a product I would recommend using. Many major car manufacturer's have recently issued memos to repairers blacklisting the use of cleaner products due to the downstream damage that may potentially be caused by them.
You should replace your fuel filter once you've finished using the tank of injector cleaner. This is most likely the problem (and could have probably used a replacement anyway). I hope this solves your problem. Otherwise you should check your fuel line pressure to ensure the pump is supplying what is required. Failing this, your injectors are probably the next most likely culprit. By this stage, things are starting to get expensive so lets hope the problem is just a blocked filter!
On a related side note; pressure cleaning an engine can sometimes cause water and soap to push down beside the spark plugs in a spark ignition engine. Sometimes this will cause the engine to run a little rough until the heat of combustion burns the contaminants away.
Hope this helps, Sherwin

Contaminated fuel tank


How could the pump failure contaminate the injectors when the fuel filter will catch all debris. Sounds like someone is trying to take you for a ride! Shop around for a honest repair shop,there out there! Have the fuel pump and fuel filter changed and you should be fine.I hate when shops try taking advantage of customers.
Good Luck hope things work out.

How do I remove and clean the fuel injectors?


The easiest way is to put a cleaner solution in the fuel tank, this will run though the whole fuel system and clean the injectors and lines.
It may smoke a little for a few miles or so, depending on what fuel to cleaner ratio you use, but follow the makers instructions.

Are fuel injector cleanings needed on an 06 silverado with only 45k miles?


wouldn't hurt to put a bottle of fuel injector cleaner into the tank. i suspect mileage isn't as important as how clean the fuel is.

Hi,

Appreciate the direct "Ask Me".

To your concern:
  • Ramping, no start - is significant. it would indicate that possibly the low fuel was agitated due to the stiff angle and dirt, sand, sludge inside the tank was stirred and got inside the intake port of the fuel pump/filter;
  • Fuel Filter - to my knowledge, there is no actual separate filter. There is a screen incorporated into the fuel pump, or in some versions in the fuel pressure regulator. Both are on top of the tank. Looks like you have to bring the entire tank down and check the inside, pump, regulator. Additionally, it may help to use a carb/injector cleaner (pls select appropriate type gas or diesel) when filling up the tank so as to clean hopefully the fuel lines, injector pump, injector, combustion chamber and valves.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.
