Mercedes Cranks but does not start diagnostics

Mercedes Cranks but does not start diagnostics

Hey guys, we got this Mercedes at the shop and the problem with it is that it does not start. It cranks but does not start. The engine turns over with no problem but the car did not want to start. We started messing with it. We tried to see if we get spark, after that we checked for engine codes and the only code stored was related to MAF sensor. However, this was not the problem. The car was not getting any fuel. It ended up being a dirty fuel filter. We have another video on the fuel filter. DO NOT ATTEMPT ANY OF THE INFORMATION IN THIS VIDEO. IT IS FOR ENTERTAINING PURPOSE ONLY!!!

To turn on the fuel pump, pull out the fuel pump relay and jumper the contacts with a bit of wire. Cheaper than buying an OBDII diagnostic gadget that works on Mercedes. The relays can also fail so if the fuel pump works, check the relay.

For everyone asking what the problem was it was the FUEL FILTER.

[kennygee]

Thank you! You got me a little further in the game. Car quit on the highway, got it towed home. Kranks, lumber is a little bit and quits almost instantly. Fuel pump seems to come on and there is pressure in the rail. I disconnected the air intake and squirted some fuel in, it started right up and ran until that fuel was used up. Now what? Fuel pump seems to be working. ECM?

If you’re replacing the fuel pump with an aftermarket pump do the harness have to be rewired. 2007 E350. My pump didn’t come with a new harness but I’m just trying to make sure it wasn’t in there for a reason. Really been trying to get this car back started because I’m using the original harness and with the new pump in it’s not starting.

How I fixed my no start was from troubleshooting with this video. My dad eventually came into help but we got it. I changed CPS to no avail although it may of been one of the problems.when you have start enable fuse fried when trying to crank it may fowl your plugs.additives like fuel injection cleaner also can clog your injectors. How I fixed it was pull the plugs cleaned a few up. Went To fuel pressure line and released a bit of gas after I pulled #4 fuse(fuel pump) it seemed to purge the gas in the lines because it seemed to be flooded. Cranking with the fuse blown I believe fowled plugs and flooded the car with gas.my dad figured trying to start with that fuse out and it did the trick.i think because it used what gas it had in the line without adding excess gas via the fuel pump. Starting fluid also helped I believe may have cleaned M.a.F sensor. But use actually m.a.f cleaner because it leaves no residue.im happy to have my car back .

Great video... I have a 2001 MB SLK 230 Kompressor... I had the same issue and changed both fuel pump and filter. However I did not change the sending unit. Will the sending unit stop the car from starting? I can spray the intake and the car will run.

Dirty fuel filter....was the cause. Cheap fix n shows how its important to keep them clean/new.

[JohnnyQuestFishing]

Thank you guys for making these videos, they help a lot. I do have one issue though. I have watched thousands of videos and I cannot find a single video on a 2005 Mercedes Benz CLK500A Cabriolet 5.0L Engine fuel filter location. I can't even find it on this service manual I have. Do you guys know where is it located ???

[rockodashpr]

great videos guys
i just bought a 2006 E350 here in FL car was runing great drove the car over 60 Miles to Bring it home no problem now a few days past and the car is doing the same thing in the video any help would be appreciated

[joelily]

Very nice video!
Is that Belgium accent?

[dimitriwalker]

I had the same issue. My problem to my issue was the fuse for the fuel pump. Once I put a new fuse it started right up and i have no more issues. I believe the fuse is the K2 fuse in the passenger side

[luckybailey]

Absolutely the best videos. I'm gonna kick my soon to be ex-boyfriend out of the way. Hes ruining my clk320. All i had was a code p0400. Now 10 days later, I'm still stuck an hour from home and he thinks he can fix it. Now it sounds like a Suzuki samurai (no offense Suzuki) and wont start and has 3 new codes. So I'll let u know how I did with ur help. I don't need help kicking his ass tho.

[mikesabin]

Or you dont have any gas in the car because the gauge could be faulty. That’s another factor

[AnytimeAssemblypros]

Nice work! Any idea: Ml 55 2000 - Long crank then shuts off...1 turn of the key it cranks for a long time then shuts off- Any idea what that can be? Thanks

[nicke]

To verify the filter is blocked, use a fuel pressure gauve on that schrader valve and if you get no pressure with the pump on thats definitely your issue

[gonzalohernandez]

When i have corrosion problems, I disconnect the affected electrical part and cleaning with sand blaster, blowing and putting dielectric grease. This one working for me.

[billclark]

Does an 1999 SL500 have the fuel filter in an easy spot to replace or is it under the seat like you mentioned?

[tatneasd]

my e500 didn't start due to blown ignition coil fuse. one of the ignition wires was damaged and short-circuited against valve cover.
