1994 Jetta

Family memeber's car.
Complained of it loosing power and quiting. Sometimes would stop but could
wait a few and restart it. Weather did not seem to be a factor.
Before it was taken to a mechanic, the timeing belt failed.

2.0 liter failed timing belt. I had head rebuilt, 2 valves. New Belt
Tensioner. Plugs, rotor cap, reassembled and ran great for about an 1 hr
(about 5 Short drives) Drove in driveway. Shut off engine. Few minutes
later, drove into the garage. Engine quit like starved for fuel. (Had been
running perfectly) Would almost restart but would stay running for more
than 2 seconds or less. Wanted to run. Checked Timing belt tension,
alignment marks everything normal. Removed the fuel input to the rail, very
little pressure. The in tank pump (only One?), runs for only an instant
at key switch on, Even with fule line removed from the rail. When cranked
it have little volume and no pressure with running into a container.
Changed the fuel filter. Still the same. Where can I check the pressure to
make sure it is the correct or how can I check the pump. Have not been able
to remove ring on pump retained but really wanted to check the filter
first.. Help. Please

The stopping, wait, restart, run some more sounds like my situation
which turned out to be the fuel pump relay. Try swapping the fuel pump
relay if you can get another one for testing. Or if you are going to
keep the car, just buy a new one as you'll eventually need one.

For testing the in-tank pump, you'll need to make a special jumper
switch (recommend adding a fuse). Get yourself a Bentley manual, it
shows you how to make the jumper plus the test procedure and flow you
should get.

On our '85 Golf, the 3 items related to fuel that failed at various
times were the fuel pump relay, the transfer fuel pump (small one in
the tank), and least frequently, the main fuel pump under the fuel
tank.

Regarding the ring on top of the tank, search this forum, there are
several solutions to get that ring off. I put a large screwdriver
against a rib and tapped with a hammer.

Good luck.

Well, replaced the fuel pump relay and it still will not start.
I removed the existing pump and checked the strainer, it was clean.
There was pressure on the line when I removed them. I also have pressure at
the fuel injector rail. I have not way of checking the pressure. I am not
so sure it is fuel now.
I see that I can purchase an online Bentley manual, but I am not sure I will
have the tools to fix the problem.
Do I need the codes to tell what is wrong and how expensive it that piece of
equipment?
Could it just be a sensor, and if so could it be one of many or just a map
for instance? It just bugs me that it almost runs everytime but just does
not stay running. Any one have any ideas?

Just replaced the fuel pump with a known good pump. Still does not start.
After cranking about 5 seconds, it appears to want to start but mever does
completely. Runs for a a second but dies out.. Help.

Just removed plug 4 and cranked, again almost started and seemed to have
plenty of spark. It was yellow, not blue.

The filter is very clean, looks new but replaced about 1 year ago. Should
the spark be yellow? I am just at a loss. COuld it be a sensor that just
failed but was intermittent ?

I have replaced many an aftermarket ign coil that just did not provide a
good enough spark.
I ONLY buy the ign coils from the dealer!!!

When you pulled the spark plugs were they wet or black?

Of course I have seen diesel fuel in gas cars too.
And they wondered why it would not start or run well! 8^o

ignition coil?

The fuel looked fine when I replaced the fuel pump earlier this evening.
The trip before last was driven by me and for a very short stretch ( less
than 1/4 mile, it seemed to surge). Drove fine after. That is why I
suspected fuel with the previously mentioned symptoms. When I removed the
plug to check spark, I noted that they were dark (rich) and seemed wet.
New plugs, rotor, cap. Once it quit is has been obviously running rich or
trying to start rich. Or is it too little spark? Is there a sensor that
could cause this?
