95 e300d stalling no start
i know there are more then one thread that has this name but i am pulling my hair out on this thing we have a small repair shop/car lot we got this car in and here is what it does..........you go out and start it cold the car will sit and idle for as long as you want as soon as you rev it up once you do that it will stall and will not start till it cools back down.......i pulled the fuel lines off at the injectors and there is no fuel......is there a fuel shut off of some sort on it (something like the cummins in the dodge trucks) please some help would be great its a nice car and i am about ready to scrap it

Have you checked the basics like fuel filters and fuel tank venting? Does it run better with the fuel filler cap off?

When the engine is running - check the exhaust for flow, it maybe that the trap-cat in the centre of the exhaust system is blocked. This is usually coupled with very stumbly idle and an engine that will cut out as soon as revved. And wont start afterwards for about 2 hours - something to do with the crankcase pressure causing the pump not to inject fuel.
Ive gone down that road. |

yes i have tried it with out the cap also replaced the fuel filter and lift pump i also cut the exhaust in front of the converter same same no change on any of them

Have you tried an external fuel source higher than the lift pump?
How about a failed IP timer not advancing fuel delivery? Sixto 87 300D |

no i have not tried that yet kinda thinking that way as well but it runs fine will idle for over an hr but as soon as you touch the gas it dies........its strange i been doing this for years and never had anything like this befor

I'm not avoiding the shutoff question. I don't know if it's mechanical/vacuum like earlier Diesels in that body series, electrical/vacuum like other MB Diesels of that vintage, or electric fuel cut like later Diesels in that engine series. Someone will chime in.

The '95 E300 still has the mechanical IP, but it doesn't have the same "stop" lever as on the older OM60x diesels... that was replaced with a button on top of the fuel filter ass'y. So, there's probably no external visual cue as to what the shutoff pod is doing - a real shame, as that's very useful for troubleshooting an issue like this.
However, it does still have the good ol' vacuum shutoff pod like the older engines. I'd disconnect the vac line to the shutoff pod and see if that does anything. Next would be leaving the oil filler cap off while revving to see if there is excess crankcase pressure that is making the pod kill the motor (sounds extremely unlikely to me, but easy enough to check). |

diesel fuel feed from a bottle and pump pushing it - see if it will rev, seeing you have eliminated all the air leaks.
Strange behaviour indeed but can be sorted out, What are the approximate rpms when it will auto shutdown? |

thanks for all the input on this guys so today i hooked up a fuel tank from a tool cart next to the car ran the same no change at all how every i did notice if played with the throttle a bit and let it off the pedal very slow it would idle again but lower then 500 rpms but it still wont start if it stalls this goes for both fuel supplies stock tank and gas can please all the help i can get is very much appreciated i need to get this thing going and i will try the running with out the oil cap........ doyou have a pic that shows the fuel shut off so i can find i have looked at the pump but dont see where it is for sure i have even talked to the dealer (i know they are a joke) and they could not tell me anything once again THANK YOU for all the info so far

Borrowing from the gsxr collection, this is a picture of a 602.962 pump (you're dealing with a 606.910) -
The shutoff actuator is the plastic turret bolted to the top of the IP. Some IPs have a metal turret with a nipple pointing out the side rather than straight up. What it looks like varies, where it is is constant. Sixto 87 300D |

95 e300 d fuel pump
That picture doesn't look a pump from 95 e300d.

Picture above - the vacuum shut-off valve is close to the "stop" sticker on the manual shut off lever; OM606 pump will not have that lever installed, but the shaft it attaches to is still there.
The fuel shut-off is on top of the main fuel filter (big metal filter) and you turn it clockwise to shut off the fuel. My bet is on leaking o-rings in the fuel system; there are about seven of them. Air gets in, kills the engine and prevents the re-start. With time it works itself to a point that allows the fuel system to self-purge when you start, perhaps there is a hot/cold factor also at work.

i have read about the oring problems these have...... where are they located at? does the pump have to be removed to change them? i also read to order them for an older like 87 300sd is that right? does anyone know of a link to someplace i could buy them from? the dealer near me are a bunch of dumb ass retards!!!
PS THANKS for all the help so far |

Actually I count 8 o-rings (boxes with numbers around them are the locations).
3 each of 601 997 04 45, 5 each of 601 997 03 45. Probably need to pull the intake manifold off to get clear access, which probably means more seals and brittle rubber bits will need to be replaced. Let us know if you go that route and need more part numbers!
