I just purchased a 1982 Vanagon Deisel in great shape but not running. The fuel pump isn't working and according to Clymers worthless manual tells you to check the relay,but dosen't tell you where it is located.Does anyone have a good electrical diagram of this vehicle and can anyone recommend a good manual.The reviews for Bentley's didn't impress me for the price. I sure would appreciate the help

Where do you live Anne?
-1)Get a 17mm open ended spanner and looosen all nuts on top of injectors and crank engine 15 times.Look to see if diesel has dripped out of each fuel pipe. No? then do next...
1) Check that pump solenoid works on back of pump. Ignition on, remove and 'dab' back on the wire on back of pump just above where the fuel lines come from. You should hear a clunk etc. If you hear nothing gently but briefly brush lead across the pump body and check for sparks.
2) Check for glowplug power by loosening red/white wire on #4 glow plug and stroking as in 1) Above.

I don't think there is a fuel pump relay on a diesel vanagon,... with the Rabbits that's a gasser thing.
I'm going to move this over to the vanagon fora.

Yup, no fuel pump relay on a diesel vanagon. Follow the checks Quantum-Man outlined (or substitute voltage checks with a meter rather than rubbing live wires around ) and it should narrow down the issue.

Clear fuel line will let you know if the injection pump is pulling fuel from the tank.
Find out if fuel is being pulled into the pump, through the pump and sent back to the tank before worrying about it getting to the injectors.

There is no gas coming out of line.The fuel pump isn't making a sound either

[libbybapa]

If there isn't any gas coming out of the line that's a good thing on a diesel.

The pump is entirely mechanical and so only pumps when the engine is turning either by it's on force (running) or when the starter is cranking it over.

You keep making comments that would apply to a gas van but do not apply to a diesel. Your's is a diesel, correct?

I am so sorry... FUEL line, this is my first deisel so it is very hard for me to refer to it as a FUEL line vs Gas line, I just figured you guys knew what it is I was referring to. Originally, I was looking for the best manual because I am in a yank to get this van running, and all these kinds of comments are just setting me back....Can anyone tell me what is the best manual for this van?????[/u]

[libbybapa]

Probably the best manual for the diesel vanagon engine is the MKII Golf/Jetta Bentley. It has much better descriptions of procedures than the Vanagon Bentley but only applies to the engine. The Vanagon Bentley would be my second choice. Haynes doesn't have any that apply to diesel vanagons nor does Chilton's. The Bentley is head an shoulders above the Haynes and Chiltons for the Golf/Jetta/Rabbit.

The fuel pump won't make any sound that is distinguishable above the starter cranking the engine over. Whenever the engine is not turned the fuel pump doesn't do anything (if it made any noises I'd be worried).

If you want to see fuel going into the pump, without the engine running; you'll have to put a piece of clear 1/4" fuel line on the output of the pump and suck on it,... or use a vaccum pump, to pull fuel from the tank, through the filter and through the pump.
This is a good way to prime the system.
Once it's primed it will often pump fuel on it's own.

It will probably do this on it's own when if you crank the engine long enough,.. but you haven't mentioned cranking the engine,... it's sounds like you've been turning the key and expecting to hear a fuel pump sound when the ignition is turned on.

I got to work/play with my first vanagon diesel engine today.
It was out of the vehicle but was still a learning experience.

[peggysgirl]

I still haven't received my manual. Does anyone have deisel fuel diagram for the 1982 Vanagon?

[libbybapa]

The fuel goes from the passenger side of the fuel tank to the filter, then to the injection pump. Then the injection pump injects some through the metal lines and fuel injectors into the engine. The rest is returned to the tank via the return line on the pump straight back to the driver's side of the tank.

[peggysgirl]

thanks for the info, can you tell me where the fuel injection pump is located?

[libbybapa]

Yup. It's the thing bolted to the top of the engine that has the metal lines coming out of it and going to the injectors.

Looks like:

Thanks so much. We actually got it running today,had to put fuel into the injection pump as it has been sitting and not running for 9 years, now we are working o the alternator,you have been very helpful..thanks
