    sorry guys my apologies, seem to be very difficult to add pictures to this thread. I will start a tread in TDIForum and then add the pictures and write-up there.

    Discovered the following after cranking the engine and not receiving any rpm readings.
    Completely opened the harness.

    The G28 sensor is connected via ws and br wire and not ws and ge as in the manuals. The black wire where is goes into the terminal for the ECM was very bad, lots of exposed wiring. Continuity problems in the wiring terminals 1 and 3. terminals 1 and 2 .004 ohms and not 1.0 to 1.2 range.

    Huh? Works pretty much the same as any other forum. See: How To Post Pictures. The only thing that might be different than SOME forums is that we don't allow your pictures to be "attached" to a post (i.e. hosted here).

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    G28 complete. Continuity checks fine. Will test again tomorrow. all wires soldered correctly and test done up to ECM connections.
    G149 tested and errors corrected. Will put everything together, connect the power and ECM up again and then tackle fuel flow tests.

    Starting to sound like a timing issue Did you recheck your timing belt properly yet? Making marks on the on old one and sprockets is not proper procedure.

    Yes that will be the next step. I still do not get any engine speed in VCDS. it shows 0 even though the wiring and the G28 sensors checks out 100%. It did discover that the the two wires coming from the sensor is switched around in their respective pinouts positions. will change them to see if engine speed is then reported.

    No start yet.
    Completed the following.
    Set up the engine according the timing belt replacement doc.
    that turned engine until both lobs of piston one in the top position.
    Locked the cam with the cam tool.
    removed timing belt.
    rotated the pump pulley until it could be locked with the tool. It had to go three teeth anti clock wise to fit the tool solid.
    used the straw method to check piston height.
    replaced timing belt with both lock tools in place.
    turned the engine 1 over to make sure everything rotates

    Engine now cranks faster than before. but still no joy,
