I replaced the fuel pump and filter..when i rotate the key it just seems like zero fuel is getting to the engine. my clutch cable blew but i jimmy rigged it with a u boult and nuts, it worked fine like this for 3 weeks then one day i was driving it and it just bogged out and wouldnt start. nothings wrong with the timing belt..not broken at least. anyone have a suggestion?

Re: 98 jetta wont start
Are you sure you have your fuel filter in the correct direction also if the pick up on the fuel pump is not sitting correctly it will not pick up fuel can you hear the pump kick on when you turn the key to the on position?

you can unhook the fuel line where it connects to the fuel rail and turn the key on and see if you get fuel but it's risky you don't want it to spill over the engine. you may just need a new filter or maybe an intermittent short at the fuel pump. could even just be the power supply plug for the fuel pump
if it runs when spraying starting fluid in it, then the most likely problem is no fuel getting to engine. check or replace fuel filter, check the fuel pump fuse and relay it may have blown. if not that see if fuel pump is working. to check pump--- have someone turn car to on, while you feel for vibration at fuel tank under car. a fuel pump only comes on for a few seconds to get the fuel to engine. but when started it runs continuously. have a good day !!
I would check fuel pressure so you can rule out pump. I had a bad pump right out of the box before. Also you may want to change fuel filter so you can rule out plugged filter. You have spark, sure seems like still no fuel.
It is in the fuel tank and normally you can check the pump by either listening for it to pressurize just as you turn the key or have a pressure test done which requires a pressure tester and you have to find out what the required PSI is for that vehicle. Good Luck
On a Digifant fuel system, the fuel pump is mounted in a reservoir
under the rear of the vehicle. The fuel filter is also in this area.
The reservoir holds one liter of fuel and is supplied by a small
transfer pump in the tank. The transfer pump can be replaced separately
even though they are installed and removed as a unit.
Motronic system uses two fuel pumps. The first is a small transfer pump
to get the fuel out of the tank and the second boosts the fuel pressure
to the necessary amount. The transfer pump is located inside the tank
and the main pressure pump can be found under the vehicle. This
transfer pump is located under the rear seat and is part of the fuel
gauge sending unit. The main fuel pump can be found in the reservoir in
front of the rear axle beam. There is a check valve inside this pump to
maintain pressure in the lines, especially on hot days, to avoid vapor
lock. The fuel filter is mounted to the side of the reservoir. This
filter has no specified replacement interval and should be good for the
entire service life of the vehicle. Whenever the ignition key is in the
on position, the pump should run for at least two (2) seconds to
pressurize the fuel lines. If the Engine Control Unit (ECM) does not
see a signal from the Hall Effect sensor in the distributor it will
shut the pump off. If a Hall Effect signal is present, the pump will
continue to run as long as a signal is detected. It is this Hall Effect
signal that signals the ECM that the engine is rotating therefore
indicating that fuel is needed. The pump is operated via a relay that
is controlled by the ECM. This relay is located in the vehicles fuse
panel. The main contacts of the relay can be jumped to run the pump
