1.6td Not starting - no fuel

Hi everyone.
I'm new to this Forum and relatively new to Diesels...
I have a 1989 B3 Passat CL 1.6td
about a week or so ago on a coldish night I jumped in the car and it wouldn't start. So at the weekend I changed the glow plugs (because it took about 15-20 seconds for them to heat up normally so when the cold nights came I just assumed they were at fault)
but it still wouldn't start. I checked the fuel last night whilst my girlfriend cranked the engine and nothing was coming through. The gauge is saying I have over a quarter of a tank of Diesel...
Not sure where to start any advice would be great...
Many thanks
Phil

Sounds like my problem: air leaking into the fuel lines somewhere, either a bad connection somewhere or an old cracked line. You can pull fuel through the IP to get it to crank if you hook up a MityVac or other vacuum pump to the return fuel line on the IP. The car has to be turned on so the solenoid on the IP is open. Then just vacuum pump till you see fuel. I've been having to do this for a couple weeks now, been too busy to try and diagnose it. Good luck!

get some fuel in a jerry can and add it. Our sending units can be suspect too. You wouldn't be the first to have a dirty/broken contacts on the sending unit.

Thanks for the replies guys. Will try everything mentioned.
Vince - excellent guide. Have tested the glow plugs and they are functioning fine - I'm not getting any fuel through.

Check that the stop solenoid is clicking.

I had a solenoid fail this summer, and it was still clicking. If you want to test it, remove the solenoid, remove the pin and relace the top of the solenoid. If it start, you have found your problem. You will have to crimp or pull the fuel line to stop then engine of course.

Harder than doing 2nd gear burnouts?
, On rare occasions I dump the clutch too fast and stall
, haven't wrecked any motor mounts yet.

Sorry to sound stupid... but where exactly is the solenoid located?
As for engine mounts I've already had one welded just above the mount where it had snapped

You brilliant boffins!
Now for my next questions...
What is the actual name for the part and where is best to buy one (uk)... or will normal motor factors stock them?
Thanks
Phil

Right... After ordering the fuel cut off solenoid. Fitted - All was working great.. for about a week...
Came to use it today and it wouldn't start again... and was just doing exactly the same thing.
I haven't actually checked yet as I had to rush off to work (without a car
) but if it is the solenoid what could be causing it to fail again?
In fact... what could have caused it to fail in the first place?
I am also having trouble with the heater... it does not blow hot and the temp gauge only goes to 70... I had been told this is probably the thermastat but having got the part could not fit it because the haynes manual is useless (as am I)... could this cause damage to the solenoid?

the solenoid is fuel related and the t-stat is a cooling part. If you are looking for a good manual, you can purchase a proper bentley manual online.
