If you are certain the fuel-pressure in the rail is within spec... then the problem is electrical power to the injectors.
 
I assime you checked all the fuses and fusable-links. It is the engine-computer that controls injection signals to the injectors.
 
Let me say that another way... the engine-computer sends the "signals" to the injectors but the bulk of the POWER comes from another source. Typically, +12 is CONSTANTLY fed to the injectors and the engine-computer momentarilly shorts the other side to GROUND to cause an injection-pulse.
 
Check for +12 on all injectors.

Sure sounds as if computer is detecting unexpected signal from engine-temp sensor.
 
Some of the engine-temp sensors up till about 2001 were found to fail prematurly. The replacement component is different design (read "more reliable")
 
On the 2.0L engine, this sensor is trivial to replace. I replaced one on my daughters car in the dark while she held the flashlight. (Dont forget to also replace the O-ring at same time.)
 
Cost for temp-ensor and O-ring was about $15 when I had to get one.

well today in my auto course we hooked it up to a gesisus scantool and it asked us to verify a code that i did not have so i guess there is no existing problem with the computer but i do have to take it to vw, and pay 110$ to get them to hook their HUB to it and print me off the faults.

We were getting spark as well with damaged ignition coil.
Apparently not enough voltage or not synchronized enough for German engineering.
Change it out, see if it works. If so then you have found your problem.
If not get a refund when you take it back.
Just don't screw it down in place and then it is not considered installed.
 
Or get one from a junk yard to try. If it works get a new one.

2002 jetta seat problem by golfergreen

I am having troble with the driver seat. The adjusment for front to back movement will not catch except at the most forward or posterior position. How do I repair it? Does it require me taking the seat totally out or can I just remove the seat cushion to get to the mechanical parts?
