I havea1998 Jetta that does the exact same thing. It is the ignition switch. I have had it replaced several times but it is a faulty part and will continue to go bad. The cure that I have found is to hold the key as far as you can turn it, and slam the drivers door. It gives the ignition switch the kick it needs to make the connection. That has worked with out fail for the last year. good luck!

03 Jetta - trouble starting by ksiggm

I have an 03 Jetta that on ocassions wont start immediately. When turning the ignition the power to the car goes out, only clicks once, then dash controls and all go off. I can open the door to the car and slam it shut again, then its good to go no problems. It resets my stero and clock but other than that no more problems for a couple days then it does it again. The only thing that happens intermittenly as well is that the clock will reset till 12:00 while driving ocassionally. There are no check engine lights on. The battery cables are on securely as well. Can anyone give me insight on how to get this fixed or what the problem may be?
 
Thanks for your help

The ONLY thing which will cause all of that to happen is losing master power from the battery. Perhaps slamming the door jiggles a loose connection enough for it to work on the next try. I would suggest that you check/clean/tighten both of the large power cables from the battery and the other end of where they connect.
 
Safety Tip: remove battery cables from battery before working on electrical system. ALWAYS remove the negatave terminal 1st and install negative last!!!

runs fine then loses power by wherejoego

i have a 2001 VW Jetta 1.8t, 5-speed manual, it starts fine and runs fine for about 20-30 seconds and then loses all power (not lighting and such but engine power). Even when bringing the engine up to 3k rpm or so it will just lose all power, drop down to about 800 rpm, idle hard and then stall. I get no response from the gas pedal when i press it to bring the rpms back up. This happens when I am idle and also when im driving, does not matter what gear I am in either. I have had previous problems with the car running rough before, bucking bad and stalling when I stop at lights. We changed the O2 sensors, the catalytic converter, and the overlay wiring harness. Each of these things have fixed the problem for a short time but it has came back.Don't know where to go next, I have read that this year has had many electrical problems, as well as problems with the ignition coils. Just hopeing for some more insight on this and possibly a solution.

This sure sounds as if it is starving for fuel. Have you checked the flow of fuel from the fuel-pump?
 
Usually this procedure involves disconecting a fuel-line under the hood and putting the end in a container. Then enguage the fuel-pump and time how much fuel comes out to determine flow-rate.

4th replacement by kravel22

I have a 2003 Jetta 1.8T. About a month ago it wouldn't start. The engine was turning but it wouldn't fire up. I had it towed and had the fuel pump replaced. It ran great for a few days but then did it again. I am having it towed yet again tommorow for the fourth time with the same problem. My mechanic called around and found out that there has been some problems with the fuel pumps for jettas. Could it be something else?

i have a 2003 jetta 2.0 and it has problems starting. whenever it is very cold outside it never starts and whenever its raining outside it never starts while it sits for a while. mechanic said he never seen anything like this from a jetta and assumed it could only be the starter and he replaced it but it stills does it.
 
also, the engine light is on and stays on. mechanic says the car has a "cold" (whatever that means) and is common for the jetta to have but wont affect the engines performance.
 
do any of u experience the same problems? and is the engine light directed towards y the car wont start in cold/raining weather? can anyone give any suggestions as to what is really the problem.

I have the same exact issues with my 97 Jetta! I hasn't been wanting to start in cold/damp weather, it will try to turn over but not 'ignite.' Also, years ago when I purchased it, the engine light would remain on, so the mechanic just permanently turned it off. It hasn't caused any issues.
 
Regarding the not-starting thing, please let me know if you find any info or solutions! Thanks!
