Question about 2000 Volkswagen Jetta TDI

1 Answer

I have a '00 Jetta. After driving approx 3 miles the car jerks and sputters. I took it to the local dealer and they said it needed a fuel pump relay. It would have been a simple repair for me, but all of the fuel pump relays I've found have 7 prongs and the one that is currently in my car has 8 prongs. From what I am understanding, there was a design change and that the 7 prong relay should work, but it does not. The car won't even turn over. Any suggestions?

Next time let the dealer put in the part so if it is not the problem you can have them take out the wrong part and put in the correct one to fix the problem. If you are going to fix it yourself be sure to get the part you need or the update kit (if that adapts the 8 prong to the 7 prong) from a Volkswagen dealer, so you know the part is correct. If the dealer installs the part and it does not work , then they are obligated to try again or even take back the part if it is not part of the fix. Sometimes the fix can involve more than one item going bad. If you fix it yourself then you take the responsibility that the mechanic was right or wrong , he or she is off the hook and only has to say "Gosh , I'm sorry that did not work". Unfortunately , most electrical parts are not returnable (unless your the mechanic in the dealership) and you do not know if plugging in the wrong part hurt other things. Have you tried putting the old part back in to see if you can back to where you were. If your car starts you may just need to get the correct pump relay (try a salvage yard for an 8 prong).

Car stalls, starts up then stalls again, starts up and stalls again


This could have several problems. #1 Fuel pressure due freezing water in fuel lines add thermal aid or rubbing alcohol . If you have access to a pressure gauge there is a service fitting on fuel rail that you can test pressure while driving and see if the pressure is gone when car dies this could lead to fuel pump electrical or more restricted lines. #2 intermittent sensor failure Mopar uses 2 sensors to control spark and fuel lose one could lose spark lose the other lose injection with a scanner they call it C/C sync ok (cam/crank) if no then check for each parameters for display.# 3 relay controls ASD and FUEL pump for voltage drops.

I was driving my jetta just now and it just turned off i was switching to third gear, didnt stall battery is good dont know whats causing the problem any ideas, all fuses are fine


Lots of possibilities.
For example you could have run out of gas.
When you turn the key on, do you hear the fuel pump for 3 seconds or so?
If not, it could be the fuel pump relay.
But it could also be ignition.
Try some starting fluid spray, and if that does not sputter, it is likely to be ignition.

From red light truck started sputtering and and stalled out


Hello. The GMC Sierra has an electric fuel pump so you should ensure that its fuses and relays are working before checking it. You may need to clean your fuel pump or replace it if your gas tank is not empty, but your vehicle has difficulty getting fuel. The GMC Sierra comes in a variety of styles and trim levels that can affect the replacement fuel pump you choose.

1993 lumina 3.1 engine. shuts down while driving,sometimes bucks at 50 m.p.h. checked plug at fuel pump harness and one pin had about 5 volts other 3 dead.swapped fuel pump relay and same thing.jumped...


the computer is what sends the signal to the fuel pump relay. Check the harness plug at the fuel pump again they tend to get loose. there is an updated replacement plug for this. also make sure the terminals on the fuel pump relay are clean and not corroded.

Everytime it rains my car sputters for a while


I believe it is an air-flow problem. I have a 2001 Beetle that did the same thing & no mechanic could solve the problem until I finally succumbed and took it to the dealer. This was a free repair for me as it is a well known problem. Do not leave it unchecked as it will ruin your cat converter/exhaust system which is a costly repair.

i had a similar problem it turned out to be a faulty fuel pump. Any mechanic should be able to do a fuel pressure test. to rule this out

Fuel system


Have a mechanic do a fuel system pressure check. You are probably having a problem with your primary and secondary fuel pumps. This should show up as a problem with a code scan, but sometimes it doesn't show at all.
