Volkswagen Jetta Starting and Stalling Issues

Comments

  • I have a 2002 Jetta TDI that will not pick up fuel when fuel drops
    just below half tank. Have checked the top side for vacuum leaks,
    etc.. Fuel gauge is correct and the problem is consistant.
    Does anyone have any ideas before I go into the tank?
    Thanks

    Sure sounds like a vacuum leak somwhere. A vacuum leak at the thermostatic "T" has been known to cause symptoms such as yours.

    If I were you , I would try replacing the fuel-filter. Pay close attention to the 2 Orings on the thermostatic "T" fitting that plugs into the fuelfilter. These 2 Orings are different size (and different color if you use German-made filter like a Mann)

    If you still continue to have issue, try using your oil-suker (that you use to change oil) on the fuel-filter to see if you can duplicate problem "manually".
  • Thanks for the input.
    I have been using after market filters. Might bite the bullet and buy a genuine VW. Could throw 5 gal. of fuel in the trunk just in case it's not the filter.
    I do have vacuum pumps and may have to start working my way back. Trying to elimate everything before going into the tank.
    Again, Thanks

  • I have a 95 Jetta manual trans that won't start after not being started for 3 months. Up until now I have have never had this problem. I am assuming it's because my car sat so long with out being started. It will turn over but not start. Any tips on how to get her to start?

    Are you touching the thrrottle pedal? If so, that may be a reason it is not starting.

    Also, check that your fuelpump is running.
  • I got it to start. All I did was put a bottle of gummout in it and 5 gallons of fresh gas. I then let it sit for 2 days and it started right up!
  • My daughter has a 2000 Jetta that has a intermittent starting problem. The car will work fine for weeks then will not start, turn the key and nothing. Some times you can leave the car sit and come back later and it starts. I have also had some luck or just timing when I tap/beat the fuse box over the battery, not sure if it has anything to do with the problem. Thanks in advance for any help.

  • 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!

    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!!!
  • 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.
  • 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!

    Let me get this straight... your "mechanic" thought that the problem was the starter, charged you to replace it, and the problem remains unchaged.

    Then, the same "mechanic" says your car has a "cold"

    GET A NEW MECHANIC!!

    As for the non starting issue, why not TROUBLESHOOT to find out specificly why it is not starting then correct that problem?

    The CEL is lit for a specific reason and is easy to find out why. Use VagCom or AutoZone can pull the codes for you for free.

    You asked for some direction about what the problem may be... YOUR MECHANIC!

    HINT: Suspect the IGNITION SYSTEM is not firing the sparkplugs. The ignitor-coil and sparkplug wires are a GREAT place to start anytime you encounter engine problems related to damp weather. In the past, I have described several times in gory detail how to diagnose.... use the "search" function across all the VW forums to get details.

    I'm thinking maybe the mechanic had the cold and actually said "code" but the poster heard "cold" :confuse:

    if you have'nt corrected the problem yet? check the keyway on the crankshaft, if this has sheared the top half of the engine won't turn with the bottom. the car will not start if the cam and crank are not in time, i would not be cranking the engine until you check this. good luck

    OK i have a 95 jetta 3 GL, I have put new plugs, wires, ignition coil, dist. cap, distributor, engine speed sensor, fuel pump, maf sensor, new belts, catalytic conv., fuel filter and done an oil change on the car! I put it in the shop to take care of the exhaust leaks that were in it and the mechanic said there was a misfire code coming up, so he checked the plugs and now it wont start!! He also said that when the key in put in and turned forward that the speedometer and rpm needsles are jumping. Does anyone have any ideas or advice??
