Alh tdi problems

So I have a 2002 alh tdi and I did the timing belt job myself and locked everything up making sure it was tdc but after the fact it was incredibly hard to get started I’ve continued to try and get the injection pump back in line with vcds after the fact but it seems like it never goes from being to retarded on the timing. When I advance it it stays on the chart for just a moment and jumps off the chart way to high to be plotted, if anyone would have any advice that would be greatly appreciated.
