Crack the injector feed pipes and turn it over until diesel comes out of all four. Tighten them up and it should go unless you have left the glow plugs out B) . The timing can't be wrong as it hasn't been touched. If you get no fuel out check the voltage at the cut-off switch. Not much else to go wrong if it is a standard Tdi. But if it is an EDC engine there is much more to go wrong, as said above.

It should be an EDC at it's age, but if Fuel is coming out I can't see much else that the EDC system would mess with

Got fuel!!!!!!!!!!!!!!!!! can see me braking thissssssssssssssssss

One month ago my 300tdi Auto 96 Jap import, EXACTLY the same problem as yours. If you look further down at the latest post on my Discofan name, I added that yesterday.This will take you though all the things I did and the helpful replies. In the end when it wouldn't start, the same as yours, and I was also beside myself as you are, I gave up and put it on a trailer and took it to the agents [can't tow automatic]. Was very worried about costs but they fixed it and charged me one hours' labour only. The fuel needed bleeding even though I'd done it 4 times myself. When I got it back it started but was difficult from cold. I tested the glow plugs with a test light and found that 2 weren't working [they were fine before the head went]. They looked perfect but only the test with the light showed two faulty[1 and 4]. It is now going a treat, hope this helps. I know EXactly how you must feel, good luck.....

Worth a try working through what was done on Discofan's.

Just as an extra the test that Discofan did with a test light for the glows is OK, but not brilliant, if the light doesn't shine then they are definatley dead, so it's good to prove they are dead, but if it lights up it doesn't mean they are working properly, quite often they start to die so the end doesn't glow and instead they glow half way up, if this happens they become hard to start but the test light would show them up as fine.

My favourite way to test them, is to pull them out, clamp the main body part of the glow plug into a jump lead, then touch the other jump lead against the thread, just be craeful not to burn yourself or anything else

I found my 300TDI was a real sod to start on cold mornings when it had EDC but as soon as I went to a mechanical pump I don't have to use the heaters (although they are connected and do work) at all.

I believe others have found the same.

When I did the head on mine I just did as Jim suggested and cracked all 4 injector feed pipes at the injector end and got the missus to turn the engine over on the starter motor until I had a good amount of fuel was coming out of the pipes and then (while the engine was still turning over) tightened each one up. I could hear each cylinder start to fire, I did start with the sensor injector but i'm not sure it matters.

Did the crank position sensor get disconnected when the head was removed? As it's connector is with the connector for the sensor injector.

I'm guessing yours is a non-edc then? My EDC needed them nearly all the time, except when you had just run the car. Even warmish days would require them.

I read somewhere that it is to do with the way the manuals pumps start, I think they kick in a load of excess fuel, hence why you get a puff of smoke from them in the morning. Mine was tricky/picky to start until I sorted the earth points and the starter, then it was perfect, no smoke at all, no struggling, instant fire up even in the coldest weather but it did require glow plugs every morning

Hi there sotal, my '98 tdi 300 auto EDC used to be a bit of a bugler to start and always needed the glowplugs until.....I fitted the Defender non-cat downpipe. Now she fires up before I put the key - well not quite but you get the idea.

I don't understand the improved starting, but I know it to be true.

Cheers

Dave
