As I recall, there are three pumps on the diesel Jetta.... One on the filter housing, in the engine compartment.....Two on the injector pump..... The head and Rotor and the delivery pump inside.... The only one I suggest you tackle, is the filter housing.
As a matter of interest, if your problem began by running out of fuel, there is a pumping device on top of the same filter housing, and there is a bleeding nipple too.... Pump the device until you feel the action becoming hard and then open the bleeding nipple and continue to pump until all the air is expelled....Close it of pump some more and while still pumping, get someone to crank the engine....make sure that the park brake is on and the gear shift in neutral....or park if it's an automatic....
If that doesn't work, then check for leakage along the fuel lines....Still no luck....A repair shop is the next stop.... I think that you'll need to have the injector pump and the injectors repaired serviced and re-calibrated.... and sorry to be the bearer of sad tidings.... That's going to be expensive....
Best of luck

NO it does not have a fuel pump in the tank. It uses vaccum.
and if their are tiny bubbles in the clear line coming from the fuel filter to the injection pump that is normal. Even when the car is not running it is normal to see bubbles in the line. hope this helps.

Testimonial: "sounds good, I'll check, I just got back from Iraq, and my wife had a friends husband work on my truck while I was gone, Thanks, love the name, Karl"
Fuses wont help. If the fuel pump isn't working, then you need to change it. Second thing, maybe its not a fuel pump, if you will describe the problem we could find out is it realy fuel pump fault.
