Did you pull the head and inspect the valves, or was this all done from the top of the engine? If the head stayed on there's all kinds of undetected internal damage that could have happened which is preventing the engine from starting...a compression test might help determine what's going on internally.
In terms of the pump timing... you have the adjustable sprocket... so you're loosening the three smaller bolts on the sprocket and rotating the pulley until your timing pin slides into the slot at the top ?

ya i pulled the head completely off and left the cam and rotated it in the work bench and all the valves came down straight. thats how ive been doing the fuel pump lol just rotate it till the slot lines up with the hole. and i cant find any one with a long enough bit to pull the injectors out:(

Diesels need fuel, timing, and compression.
Sounds like you have fuel and your timing is probably close enough to at least cough... compression test would be a good next step imho.
How fast was the engine running when the valves met the pistons?

Time for a compression test my friend.
If that's up to snuff which I doubt then you need to get the correct timing tools to set the timing as required.

The good news is that the OP has an AAZ with a pre-calibrated pump and adjustable sprocket... no dial indicator required to get the timing bang on. :wink:

Damn! I knew that. Have idi on the brain.
I still say he needs a compression test though.

How did you get the tester into the GP hole?

You'll be lucky if it starts with those numbers in anything below 0 C.

The readings are all so similar, that I'd be inclined to say that the gauge may be reading low. I have a snap-on gauge, which I believe is correct, however my adaptors are made up. First readings on my car were all 160psi. I've now filled more space up inside the injector body I used and they are all over 300psi. Car starts at -5 C. I had most of the internals to the injector [only lower half used], yet had to add washers etc to remove that 1cc. I my fill with lead and drill a pilot hole.

Are you saying the dial on your compression tester only reads up to 300 psi ??
