Our first Vanagon - A Turbo Diesel for a USA roadtrip

First u have to get the engine running. Does the pump suck the fuel ? Try it before u install the pump using a pneumatic ratchet or something.
Which screws u didnt mark ? Pics ?

Looking good, a tip though, get some dampers on the injection pipes from the pump to the injectors.
The vibration of diesel engines will crack those pipes! $$$

Does anyone know what plugs into the fuel cutoff switch? Mine was a gas can converted to the jx and am unsure if there would have been a specific colored wire, or if I can wire something up. Is it switched 12v? Is 12v supplied while running or supplied when not running? I can make a switched circuit if needed.

I think I know what your asking. The gas can is throwing me off. Yes, the fuel cutoff switch at the pump should have power with the key in the cranking position as well as the run position. If this was a diesel originally, the wire must be there. If it was a gasser, the power to coil wire would work. I think you can find key on power at the glowplug relay, not 100% sure though

On the TDI's the ECU provides power to the fuel cut off switch.

The original diesel wire is black and supports the switch with 12v when ignition key is on. You should hear a "click" when u put 12v on the switch.

The correct wiring has a black wire coming from the glow plug relay to the stop solenoid. All the wiring to convert a van from gas to diesel is basically plug and play to the wires coming to the 'black box'. You can look at the '83 diesel wiring diagram in the Bentley and it shows how it should all be hooked up. Does your van have the glow plug relay added?

Never mind. Found a diagram.

One question about wiring: where does the blue wire on the alternator (D-) go to? I imagine it is used for the tach? I have a 90amp alternator with b+, b+, d-, w outputs.

There is a power distributor of some kind that the power wire from alternator goes to. Has 4 posts. Power supply, starter power, aux power, ground. Not sure if this is what should be used? Looks aftermarket.

[Waldi]

Blue goes to the instruments shows that the alternator is working. W is for revolution gauge.
The black box looks like a relais for two batteries.

Edit: You save your starter if you fill up the pump with clean fuel before starting. I would also change the filter and fill it up.
Injection timing at 0,9mm at upper dead.
Than u open the 4 injection lines on the head. After fuel comes there u close them.

The pic shows the battery isolator that ASI used.

Timing on a 1.6TD should be 1.00-1.05mm. 0.9mm is retarded and will result in hard starting, poor power, poor fuel economy and high EGTs.

[?Waldo?]

Look it up. 1.00-1.05mm is the factory timing spec for the JX. 0.90-0.95 is for the 1.6 non-turbo engines running 130 bar injectors. Actually, I am saying the engineers were correct with their timing spec. You are saying everyone should retard their engines from the factory spec.

I couldn't care less if you have a problem with me correcting your misinformation. It's not a personal. If you feel that correct technical information is a personal attack, you might want to stay away from technical forums.

[?Waldo?]

Please post up a scan of the factory manual that shows 0.9mm as the timing spec for the JX.
