http://forums.vwvortex.com/zer...id=22# I don't understand injector pumps enough to solve my problem. I replaced the top seal for a leak started the engine and a week later the next seal down leaked. I replaced that seal but engine would not start and i noticed the round head seal was leaking so with a diesel geeks tool I replaced that one. Now engine will not start but their are no leaks or bad noises. i took the lines off from the pump to head and careful about the high pressures noticed irregular sprays some hitting a cardboard 4 inches away and some dropping half way. I used a vacuum pump to pull out the air. I tried to start the engine with wd40 which works with my truck and merz diesel but did not work on passat. Any suggestions? Pump has about 200,000 miles on it.
