Default Continued starting problems>>>

So I norrowed it down a little bit.

When the fuel tank is full I don't have this problem. But once there is less than a 1/4 of a tank the hard starting problem comes back.

Any ideas????

Any possibility your FSU (fuel sending unit) is wrong (cluster problem)?

Default Maybe the fuel pump isn't reaching all the way to the bottom of the tank? >>>

Separate question, did you ever check the fuel pressure?

The fuel filter is good?

Default Interesting. My friend's GTI starts to sputter at AutoX with 1/4 tank. I told him to relieve

vacuum next time instead of lugging in another 35lbs to get around it. Our TT works fine till empty except I have no n75 control when the ECU gets too hot (already narrowed down the problem)
