Let me again say thanks for your help.

After replacing the engine speed sensor/impulse sensor I tried
to start the engine, but no change, still will not start. Just cranks.
I checked for spark and it was very weak so I swapped my coil
with a friend who has the same year, same engine same manual
trans Jetta and my car started but that is it. Starts and dies.
Starts and dies. no matter hiw many times I start it.

The engine speed sensor/impulse sensor was bad, I checked
for the 400-1000 ohms resistance between pin 1 & 2 but I had infinite
resistance so I know that part was bad. I can smell fuel so I am guessing
that isn't an issue. I checked the injector pulse with a noid light and they
fire normal.

Any clue why it would die right after starting?

I just looked over this again from the firts post you said you ran out of gas.

you put gas in it and it wont start.

do you hear the fuel pump run when you are cranking.

pull the fuel line off th efeed line to th efuel rail to see if there is fuel coming out while cranking.

if not smack the bottom of the fuel tank with your HAND. See if the fuel pump starts again. If so there is you problem have seen maney fuel pumps just stop running. It is still a electric motor with brushes and a commutator that can lock up do to bad conections.

yes I do you have a immobilizer that has been set your car is 2000 and higher right.
on your dash there should be a car that has a key in it is it flashing. if it is you have to have the dealer reset the immobilizer. they will need all key that you have for the car to do this.

sorry no one else can do this for you.

Why would the immobilizer have gone off?

The cost of towing the car and paying the dealer will pay for a VAG-COM from Ross-Tech where I can program
the immobilizer myself and have it for future use.

Someone on another forum suggested disconnecting the battery for a few hours then reconnect, insert key to
acc position and wait 15 minutes. Does this really work??

As for the Ross-tech you have no way of doing it.

VW has the only means to reset it.

you need a vw login pas code and then the tech has to in put his own info that is taged to his SSN #
so that if the car or parts where stollen they can trac back who programed it last.

This was VW way of tell the Goverment they should be the only ones to do this.

For customer protection of the car and or parts on there car.

Sucks I know Evil or Very Mad , I Have had a VAG-COM since it came out even when I was working in the dealers. All the way up to being head man in Charge in the shop.

the Tool is good It works better than the VAS tool but Not great yet It will get there.


As for unhooking the battery and turning key on ACC postion has never work to my knowledge.
It works for radio codes if the radio has not been removed.


But not for Immobilizers.

sorry Sad

Well, I tried the 3 hour trick disconnecting the battery
and leaving the key in the ignition turned to acc for 15 minutes
before attempting to start the engine and presto, it worked.

The car started and runs ok.

I returned the coil to my friend and bought a new one for $230
and started driving.

About an hour later the damn check engine light came back and
the code was for cat efficiency, I don't remember the code and
in my annoyance, erased it. I hope it doesn't return but if it does
then I guess now it needs a cat.

Wonderful.

I wanted to say thanks.

You were one of only a handful of people willing to help
between this and another forum.

I reset the DTC and so far, so good.

Again---thank you.
