Check the injectors. They are really bad about leaking on the 4.3's.

have you considered checking alternator and battery? just a thought

sounds like a fuel pump problem,with fuel pumps u can have pressure but not enough volume,try goin up a steeper hill in 2nd gear and get about 3000 rpms on the engine and see if it really drops out bad and is really gutless,if that happens without a check engine light coming on it might be yur pump and u should also replace the fuel filter at the same time,hope this helps

SOURCE: cranks but won't start like it has no gas

Sorry to burst your bubble but a 97 jetta no matter what model including the trek I and trek II dont have transponders in the keys that didnt start untile the 2000 jetta's
