Thread: Injection timing on 1999 300 Tdi????

I'm not mechanically skilled enough to offer direct advice, but reading your problem reminded me of the thread below:

http://www.aulro.com/afvb/discovery-...ont-start.html

I think the injector pump was wired 180 degrees out in this thread.

Some of the things I have done that prevented my 300tdi from firing:

1/ Cross connected the lift pump
2/ Failed to connect the fuel stop solenoid
3/ Not set the valve clearances properly.

since a 99 tdi should also have EDC (Electronic Diesel Control), the ECU should also get power, although I haven't played with one of them.

Provided the timing belt, Injector marks, cam and crank are in their proper positions - and if the crank is locked at the flywheel and the pin is in at the injector pump you can't go wrong - you should be seeing something at tdc.

If you have the time, buy a RAVE disc from the markets section - having a workshop manual on PC is a wonderful thing when re-assembling the engine.

It will only have EDC if it is a special import car/engine, I don't believe any were orginally sold in Oz.

Wow! I wasn't expecting such a swift response, it was most appreciated. I have since been in touch with the injection specialist who carried out the calibration and checking of the pump in question. After some difficulty he did admit that it is entirely plausible to stuff up the pump timing in the process of checking it. The reason being that in order to fit the pump on their test bench, they have to remove the front pulley that just happens to be a taper fit with no splines. This obviously allows for the timing to be anywhere within a 360 degree radius if they are not taking care of what they are doing. He also informed me by way of an excuse that the injector pump on the Land Rover Defender is exactly the same but with the injector pump pulley 180 degrees different to the Land Rover Discovery (which is what I have). I also managed to get out of him how to set the pump up but am hesitant to carry out the work myself as it is not my vehicle and I don't want to stuff it up, but I will have a look at it before I send it away after removing it ... again! Thanks again for all your input, I will post an update when the vehicle is running!

P.S If any techno-minded bravehearts want to know how to time up the pump just let me know.

Hi Ben,
Search through the thread that was mentined in a previous post, it has ALL the info you need to know about setting pump timing.
EDC pumps were not sold in Aus,(Thank goodness) and there is no truth that the Defender pump is different in any way apart from fuel settings/ calibration from the factory.

got it covered, as mentioned by nice1guv, in this thread.

in particular these posts within that thread
post 15 covers the initial priming and diagnosis
post 27covers the initial diagnosis
post 38 broadly covers coarse timing/phasing
post 39 broadly covers the pump being timed wrong to the cam
post 44 details how to work out the coarse timing/phasing of the pump
post 58 has an image of the belt timing
post 63 has better images of belt timing
post 70 Describes the phasing of the engine in the thread
post 80 details the field work around for an incorrectly phased pump
post 84 reveals the solution in this case


Read the whole thread and if in doubt ask questions. better yet, purchase a rave off of Incisor

Thanks everyone for responding. I sent pump to Diesel Specialist today and am hoping the pump will return timed correctly. After reading all the threads you posted and looking at the photos I am certain pump timing is the problem. If I manage to pull myself away from the celebrations I will drop a line on how she goes when bolted back together. Thanks again Orbvious.
