Ok I am new to this forum and it seems to be very helpful. I could not find the answers i need so i am posting a new thread....
My dad has a 1998 TDI Beetle with 110k on it. It has been a great car and we want to keep it that way. It has been getting harder to start in the past 6 months so I have replaced the glow plugs, and installed a lift pump on it. The car did not come with a fuel tank lift pump so i installed one on the frame rail. The car seemed to start much easier after that.
Now I have a fuel leak on the rubber cap by the #1 injector. The cap was brittle, so I replaced it. It is now leaking again? Is this for the return fule pressure? It has a lot of air coming out along with the fuel.
While I was diagnosing the hard start issue, someone told me to clean out the intake. So I have successfully cleaned the intake and it runs better once started, but still very difficult to start!
Not sure what to try next! Please help!
