Clogged fuel filter, clogged fuel lines at fuel pump, bad injection pump.

To check the timing belt position you must set the engine to TDC and inspect the index marks. See this article for details:http://www.myturbodiesel.com/1000q/a4/ALH-engine-timing-belt-change-VW-Jetta-TDI-1.htm

It could also be a clogged intake or intake valve (anti shudder valve) closing. see this article: http://www.myturbodiesel.com/1000q/a4/clean-intake-manifold-VW-TDI-carbon.htm

Lastly, check for all codes and for broken vacuum lines. The EGR, turbo, and intake valve are all vacuum controlled.
