Thanks Andrew,
    There is only one mark "notch" on the D24 pump sprocket. I found the email from Loren. I thought someone said something about 180 degrees off. I bet that is my problem. I just know it is. Thanks everyone for your help. Ill let you know.

  Is your pump 180 off? First time I did one I had similar problems and it 
turned out the pump was 180 out. Set right up after that.

  Can the injection pump be 180 degrees off. How many rotations does the pump have before it goes to the start position. Do you understand what I am asking? If it takes one cycle to get back to the start then it cant be 180 deggrees off, but if it takes two rotations it can. Thanks 

It can be 180° off.  The pump rotates one complete turn for each two complete turns of the crankshaft.  On the VW there are two marks on the pump pulley 180° apart.
