Hi, new guy here. Hate this to be my first post but here goes. Reference car is a 2003 Golf TDI. I changed the air filter, oil and fuel filter today. This being my first diesel car I didn't know to purge the lines of air before starting. After tryng to start it a few times I get on this site and see what I did wrong. I fill up the filter with some fresh diesel and it starts. I drove it to Home Depot and it wouldn't restart after I got back out. I walked home and got my truck, can of diesel and some tools. After getting no where back filling the lines, I figured my problem was in the pump itself. I bought a bicycle style pump and hooked the suction side to the line off of the T. After a lot of pumping on it, it still does not start. No stumble or anything and now the battery is starting to get drained to where it is not cranking as hard as it did. I am at a loss as to what to do next after this frustrating adventure.
