Fuel injector problem - 2000 Jetta

I have a 2000 Jetta GLS, I was told by the dealer that they could not get to fuel injector #4 to close, there, gas is getting into the oil. I was told that the ECM needed to be replace because it was not sending the signal to the fuel injector to close. Any idea on how this problem can be solved without pending $1,200 for a new ECM<

Too bad you are not across the street from me.
The injectors are 'fired' by power transistors in the ECM that can be individually replaced but I doubt the dealer has that capability. It could also be a failure in the control circuit before that last stage but one can't tell without a little measurement skill.
If it is only a failed power transistor, they cost < $5 US.

Rough idle and smells like gas when driven


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.

97 VW Jetta GLS, manual transmission. The speedometer stopped working & the fuel gauge is jumping around.


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

What should i check on my 94 dodge shadow if it has spark rolls over but wont start.


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

My 2000 VW Jetta won't stay running


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

2000 Jetta stalls after 15minutes


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.
