the fuel pump and timing belt are not components for spark did you check distributor- points -coil -plugs-wires ignition switch -fuses and relays ----didnt specify engine if diesel need to check glow plugs

You have a open connection somewhere.

what gear. where are you and what are you doing. combis?

You should be able to go to your local library and find a wiring schematic if you can find it ask for help they some times have direct links to the factory manuals

the gearbox is really worn--like the shifting fork that works the gear teeth--have someone push u with clutch in then let it out-it may jar it loose--if u du then just use the other 3 till diagnosed

Have the fault codes read for faults Replace the faulty units with genuine onebecause most aftermarket units are not set for OEM cpu units and are notcompletely compatible.

wierd not normal. are you sure you have eased off the throttle enough just before you dip the clutch, diesels can lag slightly, is it a turbo? turbo could create even greater lag

The procedure is given in the Hayes manual. You need to turn the cam shaft gear so that the front valves (two valves close to the gear point up) are close and the notch on the cam shaft other end is horizonal (side facing the battery). You need to bring the flywheel (in bellhousing) to top dead center (you will see a notch on flywheel and a fixed pointer on the bellhousing. The notch should be in line with the ponter. After that, you need to bring the injection pump at certain pisition. Then you can mount the belt. It is not a difficult process, I have been doing it, but you need certain tools that will make it easy, such as cam lock position tool, injection pump lock pin, gear remover, etc.

looks like your 85 jetta actually has both pads and shoes. you can look on autozone.com and find more info.

Your fuel cutoff switch on these engines are located on the fuel pump itself right by the injector lines and takes an 8mm wrench on the nut for the wire.

No they did not. A diesel motor does not have a distributor (no plug wires etc.).

try flushing the heater core out ,if that doesnt work a piece of cardboard in front of the rad

VW dealers have a special "tool"to set up the gear linkages.....its not easy to set up by adjusting one part then another.....in fact its bloody near imposible.

YOU HAVE A 12 POSITION POSITION IS LOCATED BENEATH THE DASHBOARD NEAR THE STEERING COLUMN OR LOCATED IN THE LUGGAGE COMPARTMENT AND SOME ON THE AIR CONDITIONED MODELS.LOOK FOR A BLOWN FUSE THAT MORE LIKELY THE THE FUEL PUMP FUSE.IF YOU REPLACE FUSE AND IT BLOWS AGAIN YOU HAVE SHORT IN FUEL PUMP WIRES.

you need to replace your clutch .adrian,,,,

The diesel is quite a simple system. Just fuel and compression. No ignition to worry about. However there are a few things to look at.

If you have the glow light going on and turning off to confirm heat at the cylinder then it is not a glow plug. Even quite cold is should start after a few turns as the compression builds.

Fuel. Pull the fuel supply from the connection at the first injector (right hand side). Turn the engine over. If you have fuel there then it is not fuel.
If no fuel then you have a problem with the fuel pump or filter. Filter is on the lift side of the engine near the air filter. Loosen a line and check for fuel entering an exiting the filter. It should have flow in and out.

If you have fuel to the fist injector then you most likely have a compression problem. That is a head gasket. If a head goes on a diesel the compression is not high enough to ignite the fuel.

This is where I'd start looking. If I can help further just ask.

Please rate this answer.

Thanks, Adrian

There are several depending on what you are looking at. I have not found a good set via the internet unless you want to order a set or purchase a manual.

The best source is a manual. The best is Robert Bentley version or the Haynes. I got mine from the library. Go and ask and if they don't have one they will often be able to get one from another branch.

Sorry but if I scan and send a copy if violates the copyright for the manual.

It is best anyway to have a copy at hand and to see the full set of diagrams.

Hope this helps.

it is posible, is not isy but not imposible. buy the proper clutch cabele for your jetta
