VOLKSWAGEN JETTA FUEL FILTER PROBLEM

1990 Volkswagen Jetta • 16,600 miles

Hi, I have a 1990 VW Jetta that acts like its starving for fule, it sputters out and it stops when I give it enough gas and I get the RPMs up. What could it be?

I'm guessing your car has Digifant Fuel Injected. There should
be 2 fuel pumps, one under the car by the fuel filter and one
inside the fuel tank.

If the one in the tank fails, you can have power / stalling issues.

Faulty ignition components can also cause similar issues.

Checking fuel pressure at the injector rail will not be enough. Both
pumps need to be checked for flow & current draw.
