1996 VW TDI Passat not starting, not getting fuel to cylinders
1996 VW TDI Passat. There is deisel present at the inlet to the injector pump, but no fuel going to engine. I loosened one injector - no fuel.
Car was sitting unused for 2 weeks, and needed a jump to get battery recharged. Hope I did not hit it with too much voltage with the charger. Almost seems to be an electrical problem, but I do not have a schematic or manual, so not sure what to look for. Is there an electrical command to the injector that controls when it will turn on?

Consult the Owner's Manual, or view the oil specifications on the fill cal or dipstick (usually the fill cap) located under the hood. Depending upon mileage you may not want to vary from manufacture specifications, or risk voiding your vehicle's warranty should any remain. The VW TDI's are typically high maintenance engines. I would strongly recommend staying with the manufacture's oil specifications, and do not overfill the oil in your vehicle.
It could either be the engine speed sensor or the fuel injection pump. When this happened to me, ofcourse I was in the middle of nowhere. The fuel injection pump needed replacing. To do this they had to also time it... I let vw do this one reluctantly.
It is on the passenger side right behind the washer fluid fill tube. You can follow the fuel lines (look like 1/4" black tubes, some are clear) from the injector pump to it. It is a caniser a bit bigger than a normal looking oil filter and sits between the washer bottle and the metal that forms the wheel well. It is held in by a screw type clamp about half way down the cylinder. Probably isn't the fuel filter unless there is air in the lines to the injector pump or they didn't bother to fill the fuel filter up with diesel after putting it in. There is not a fuel pump in the tank in these cars so everything is sucked up by the injector pump and it needs to be primed properly.
When you open the hood / bonnet and look at the engine, the fuel pump should be at the left hand side of the engine block. One end is hidden under the cam belt cover, and the other end has 4 steel pipes coming out of it leading to the fuel injectors in each cylinder. There are plenty of other fuel pipes leading to and from the injection pump.
