IMO, start off by opening gas tank, pulling your Fuel Pump fuse (In my w220 2002 S55 AMG that fuse is located under the rear passenger side seat) and then start your car (It won't start, instead it will release pressure). Then optionally if you have someone to help then you connect/tap into the fuel line (Used for Fuel Pressure tests and right where the coil rack/rail is). As you're removing the hose from underneath, they can either release pressure from their end so you don't have fuel squirting out desperately or if you want to be a little more clever you modify the fuel pressure test hoses to have a suction type vac so the helping person can pump lightly to suck up fuel while you undo the hoses so nothing gets messy.... Just some food for thought that makes sense to me theoretically. Somebody please correct me if I'm wrong.

[@markb881]

Thanks - spot on instructions! My hose clamps were garbage but I only had one gusher - got everything changed and hopefully this solves my intermittent long-starts!

[@piscatawaymechanic]

glad this video helped! if you can buy a obd2 scanner for your mercedes.. you hook it up under the dash on the driver side . or you can also go to any autozone and get them to do a free obd2 reading .. these fault codes will lead you to anything wrong with your car . always start by doing that first. because these cars can get out of hand financially if you misdiagnosed mechanical issues.. mercedes are 60% hardware 👨🏼‍🔧and 40% software 👨🏼‍💻

Im having same long starts, did this help you ?

[@napalmspears3016]

Thanks you just saved me a few hundred buck's👍

[@piscatawaymechanic]

Glad my video helped you out 😀👍

My takeaway in the 1st minute of this video: Let your emotions frustrate you, and make frustrating decisions that include frustrating cost

[@petescarport]

Thanks bro. I have to get to fuel pump to see if power is getting to it. I got car and same day it stopped starting while I was checking fuses. Not sure if a random fuse or relay is bad but I checked them all and now neeed to check pump. I actually hope it’s the pump so i don’t have to chase electric issue any longer

[@piscatawaymechanic]

If you can get a obd 2 scanner and plug it into the car .. scan for any fault codes that the car is tell you needs attention (Do this first ) If you don’t hear the fuel pump make any noise then it could be dead.. test the wires is good to do also ..

Thanks

[@nobombs8784]

LOL the guys totally showing a fuel pump and calling it a fuel filter perfect example of KZbin people that shouldn't be talking

Do you have any instructions for changing fuel leveling sensor 05 s55

[@piscatawaymechanic]

Unfortunately I don’t..

[@davidcarter3066]

2002 Mercedes s500 gas meter is broken what do you think it may be? I brought a new fuel sending unit haven’t tried it on yet. But if that doesn’t work what else you think may be the issue? Thanks.

[@piscatawaymechanic]

A new fuel sending unit could help If that doesn’t do the trick. It could be your speedometer until failing to receive the signal .. you can also check for any obd2 codes currently active that could indicate a potential problem.

[@davidcarter3066]

Thank you will try that and keep you posted.

[@matreyia]

Those are single use clamps. You are supposed to use worm clamps and replace the oe single use clamps.

[@weaza.p.k.436]

Is it common for the fuel pump to leak fro the side where they wires connect

[@piscatawaymechanic]

No leaks should be happening at all ..especially when gasoline is involved ! I would recommend replacing that pump ASAP .. check your hose lines make sure they are soft and flexible. Replace them if they are hard and or cracked at all .. and sometimes the hose clamps lose the ability to hold tightly and can cause leaks .. Hopefully that helps you!

[@weaza.p.k.436]

@@piscatawaymechanic yea I don’t know what happened it just started putting gas out one day and when I got under there it looks like it’s coming from the fuel pump but all the hoses are good

[@greglopez7768]

Been following your channel and have learned a lot bout my 01 S430.. Now the problem I'm having is tht my fuel pump is working intermittently sometimes pump kicks on sometimes it doesn't and has left me stranded twice but then next day fuel pump will work and can starts fine this is driving me nuts please help!!!??

[@piscatawaymechanic]

Well I would suggest first hook your obd2 scanner into the car.. check for all fault codes Then secondly, check fuel pump fuse ( i have a video of the diagram/ fuse locations on my channel).. thirdly. Check the leads going to the fuel pump for voltage..if everything checked out ok then its definitely time to get a new fuel pump.. make sure to get the Oem or like the one i have. Because cheap aftermarket pumps are very noisy and fail prematurely!! Hopefully this helps you

[@greglopez7768]

@@piscatawaymechanic did all the above except checking leads for voltage, i must admit I did install a cheap fuel pump bout 1.5 yrs ago and it is always noisy

[@greglopez7768]

@@piscatawaymechanic BTW it's not throwing any check engine lights and i also swapped the fuel pump relay and nothing yesterday, however today the fuel pump fired up and car started just fine...

[@piscatawaymechanic]

@@greglopez7768 well the check engine light in Mercedes is for vehicle emissions related faults. W220 are essentially 50% governed by computer programs /algorithms Yeah sounds like your fuel pump could be on the way out. But wait and see what codes are screaming for help on ur obd2 code scanner first . You will be surprised 😯 at the amount of codes. Thats why people just throw in the towel when dealing with an w220 😑🤦🏼‍♂️..

@@piscatawaymechanicgotcha didn't know it only picks up emission stuff thanks for your response, do they use OBD2 scanner at the local auto zones n stuff?

I've a 93 sel 400 luv it. But high speed wobble at 55mph only...any ideas..

[@piscatawaymechanic]

I would say , check tires , rims,ball joint, tie rods , and all bushings.. that will help find the issue

Having a difficult time picking out either Bosch 0024773001 or the original Mercedes from FCP.. Help? I'm going to assume the Bosch since it's more expensive and also a trusty brand.

Filter or fuel pump?

[@yachtkuza]

@@piscatawaymechanic The following part number above would be for a fuel filter.

[@piscatawaymechanic]

I chose mann filter.. mann , bosche , Mercedes are all very good.. the most important thing is to replace the filter on schedule so it can provide good filtering..

[@yachtkuza]

@@piscatawaymechanic Oh for sure, but I'll only use Mann when I'm flipping cars to cut cost down.

[@jamespowell617]

What are the symptoms of a failing fuel pump or filter?

[@piscatawaymechanic]

Ive seen. Hard starts, very noise pump , no sound from the pump once its dead , could signal a code in the obd2 system.. filter changes can be done every 2 years .. most people neglect this simple replacement item. Fuel pump & filter are not extremely expensive so it you want to replace it for good maintenance habits…. Please check for any obd2 codes first ..this will lead you 90% of any issues 🧑🏼‍💻+🧑🏼‍🔧=🚘

[@jamespowell617]

I am having problems when turning ignition it cranks for a bit and engine fires really late.the car always starts but the overcranking and delayed ignition is concerning. What would cause this?

[@jamespowell617]

Can you recommend a good scanner ?

Hola porque decidiste cambiarla?

You skipped a major part on a lot of people don't know how to pull the clip off the fuel pump the electrical

You shouldnt be working on a car if you cant figure out to disconnect a plug lol

[@dracoyay6577]

My fuel pump is not coming on at all

[@dracoyay6577]

I even changed out the crank sensor still nothing

[@piscatawaymechanic]

@@dracoyay6577 #1 hook up ur obd2 code reader under that dash .. see what fault codes are in need of fixing. #2 check the fuse #3 listen and see if the pump is turning on when u turn the ignition on( you should hear a slight buzz) #4 you can check the lead cables going to the pump with a voltage meter to see if its getting electricity .. other then that I would go ahead a order a new pump just to be prepared..

[@dracoyay6577]

I can’t find the fuel pump fuse and I got under the car to listen and it isn’t making any noise i changed out the pump and filter all brand new still nothing

[@dracoyay6577]

My voltage meter ground says positive number but the red wire says negative numbers

[@piscatawaymechanic]

@@dracoyay6577 ok the fuse for the fuel pump on 2000-2002 s class is located beneath the rear passenger side it will have the light on it. Once u see the fuses look for relay (T )its a large relay .. after replacing that with a new one. See what happens then. If u have a voltage reader checking the wires for any voltage is important before and after.
