Fuel injector problem - 2000 Jetta

When checking for Vacuum leaks, did you use a water spray bottle on seams and vacuum lines and EGR pod?(engine running)

Check for air leaks in exhaust before O2 sensors. O2 thinks its running lean from air leak in exhaust header and enrichens fuel charge.

Fuel injectors dirty, not closing tight. Switch injectors to other bank and see if Error Code moves to relocated injectors.

Bad spark plugs, check if you have fuel runners in your intake.

There are only 3.
Transmission mount on drivers side, motor mount on passenger side, and dogbone mount underneath.

Hi Ken You seem to have two faults with your vehicle. One will be a speed sensor and the other possibly a bad connection. Take the vehicle for a diagnostic scan and pin point the problems (which the scan will do) and then sort them out. Regards John

yes you have an inline fuel filter on your car.

Jetta GL & Jetta GLS (two versions with 2.0 l and 115 CV engine)

2000 Volkswagen 2.0 liter SOHC L4 (AEG)






Jetta GLS VR6 y Jetta GLX VR6 (2.8 l VR6 and 200 CV engine)

2000 Volkswagen 2.8 liter DOHC V-6 (ATQ)




Hope helps.

FIRST IF IT IS A 4 CYL TAKE OFF THE AIR CLEANER BOX AND CHECK FOR THE THROTTLE BODY INJECTOR TO SEE IF YOU ARE GETTING FUEL , IF YOU ARE THEN ITS A TIMING ISSUE AND MOST LIKELY WILL NEED A TIMINIG BELT REPLACEMENT IF NO FUEL CHECK THE FUEL PUMP RELAY AND THE FUEL PUMP, IF IT IS A V6 CHECK FOR FUEL PRESSURE AT THE FUEL RAIL BE CAREFUL THOUGH PUSHING IN THE VALVE WILL SPRAY GAS SO BE CAREFUL , IF NO GAS THEN CHECK THE FUEL SYSTEM

COULD BE STOPPED UP FUEL FILTER.WEAK FUEL PUMP.BAD SPARK PLUGS AND WIRES.IDLE SPEED TOO LOW.BAD FUEL INJECTOR.TO SAVE YOU TIME AND MONEY HAVE VOLKSWAGON PCM SCANNED TO LOOK FOR ANY TROUBLE CODES.

not the fuel relay. the pump may not have enough psi to pump properly. and you ould have a blocked fuel filter/ ethanpl das has been none to clog lines,fuel pumps, and emissions.and injectors. <p>
Change out your fuel filter first. Add a can of SEAFOAM to you fuel(parts stores). after changing filter. let SF sit in tank for 10-20 minutes in fuel. It will help dry the water that ethanol produces..,<p>
If it turns over faster, and wants to start, that is a sign of EGS(ethanol gas syndrome)/ let it sit another 20 minutes and try to start. If it won't fire through the injectors, replace the regulator(which is also damaged), and that should fix it. Also have a psi done on your fuel pump. good luck

lol inside the gas tank

I heard of an issue with the fuel pick up in the tank. It has a check valve that gets hung up or freezes in the colder climates.
