Question about 2001 Mercedes-Benz C-Class

1 Answer

I have the same problem.

Mine is a diesel & it takes a good few times to get it started.
I had a new fuel pump put in a little while back. Could it be that it wasn't fitted correctly or another problem?

I would suggest a glow plug issue or the unit/relay that heats them up. If the glowplugs dont get preheated enough a diesel is very hard to start and may run poorly until it gets up to temperature.

Fuel pressure could be it but if it ran fan when you picked it up I would doubt it. You may want to change the fuel filter as some debris may have been knocked loose in the whole process.

The fuel filter light comes on to tell you that there is Water In The Fuel tank at a level high enough to be picked up by the fuel pump. Your problem is a fuel delivery system that is full of water. Drop the tank and clean it out first. There is a very specific procedure for replenishing the fuel system with good fuel. The best thing to do is pick up a copy of Haynes Diesel Engine Repair Manual, Part #10330 as it outlines the procedure. However, if you are unable to get the book reply in the comment section and I can type it out for you. It requires 14 steps.
While you are doing this it would be a good idea to also replace any and all rubber pieces of fuel line. They have been known to collapse over time, when the pump comes on. Make sure you get fuel line that is diesel specific, regular gas line won't work. You mentioned replacing the injector pump so it will need to be taken to a diesel shop to be re-timed. Timing involves tools that are expensive and not normally accessable bu you and I.
The Hanes manual is an excellent investment at about $22. It provides excellent repair procedures for your engine as well as some service up-dates and shortcuts.

Landrover tdi 110 fuel pressure non start


When you run a diesel engine out of fuel ,it needs to be primed in most cases,see if you can locate the fuel filter and and fill it with diesel fuel,And depending on the yr and make, your engine could be demanding higher pressure then you would think is normal from your lift pump in the tank.

Well it should start ok but i think you may have a problem with it drawing in air along the fuel line somewhere ,normally this is caused by a deterioration of the flexible fuel lines on top of the tank and into the injector pump ,another little tric i do when i have starting problems is to fit one way non return valves in the feed and the return pipes as close to the injector pump as i can get them .A diesel engine will not toleratre any ingress of air on the intake side of the fuel pump

I'm a little confused. You changed all the fuel filters? How many do you have? If you have a late model vehicle, then your fuel pump is in the fuel tank. How did you put an in line filter before the pump. Is your vehicle gas or diesel?

Hey bro, your diesel pump might be on the way out but here are some things to check and do and see if they help.

Replace the hoses going from the pump to the diesel filter with new ones.

Use fuel injector type clamps, NOT gear clamps they don't tighten enough to stop air not getting in.

Change the diesel filter, and make sure the drain on the bottom of it, if it has one which most do, is nice and tight.

Air bubbles in the injection lines are usually a sign of a weakening injection pump but I ran mine like that for a long time, the air works it's way through. Are you leaking any diesel? Maybe check the returns to the tank. Cheers bro.

First of all, YOU MUST HAVE ALL FUEL LEAKS REPAIRED BEFORE TRYING TO START MOTOR.!!!!

If you by any chance get the car running with all those leaks, you will be exposed to have a very serious accident.

After your leaks are repaired, we'll be happy to help you to start up your vehicle.

Good Luck,

The next step is fuel flow measurement. your description sounds like fuel starvation...this test focuses on volume over time.
