My 2003 TDI vw is losing the fuel out of the fuel line and I do not know why can not see any leaks. The car just will not start after it sits for a couple of days. I can bleed the car threw the injectors however this is a real pain in the ***.

Check for an air leak in the fuel line from the tank.

Question moved from Spanish car maker 'Seat' to Volkswagen Jetta.

When were the glow plugs last changed?

They sit over the cylinder like spark plugs and warm the diesel before it goes into the inlet manifold, greatly assists starting.

When was the last time you replace the air and fuel filter????Fareed

recheck fuel line routing

If it starts when pulled by other vehicle then Glow Plugs. othervise check the Ignition Key Contacts, might be worn out.

I neither of those then give me some more information. What exactly engine it is, maybe u know engine code.

when you checked the fuel line fuel flowed when u tried to start the engine while the fuel line was disconnected from intake? have you checked the injectors? are they spraying fine or there's no command.

Hello, I have something that might help you. If you know where your fuel line goes into the engine. I would let it sit overnight and then take the line loose. Then hold the fuel line into a bucket and have someone turn on the key in the car. This should tell you how fast you are getting fuel up to your engine. Your problem sounds alot like its not getting gas up to the engine fast enough. I would check these things:

1. Fuel Filter
2. A bent or crimped gas line. (From Engine Rebuild)
3. You could even have a blockage in your tank ventilation. This would cause a vapor lock not allowing the fuel pump to work properly.

Outside of a fuel issue from your previouse history It could be still in your timing. If you find my information helpful please rate me and have a great weekend! :>)

check cattaletic converters may be pluged up cause to much back pressure which would resault in exsessive cranking

ther is a delivery pump in the tank that feeds the injection pump.
typ TDI club in your seach ther is great info on this

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.
