Question about 1991 Volkswagen Jetta

1 Answer

91 Jetta starts hard and occasionally stalls out

I have replaced the battery, new starter, new plugs and wires. It continues to start hard especially after it's been running, I've stopped and try to restart. Sometimes when I am driving, the car loses power, not driving power but the lights dim and it runs a bit rough. Almost feels like something is grounding out. Then there's a horrible screeching sound, like a bad belt. Once the screeching stops, car drives fine again and has full power.

Sounds like your alternator is starting to seize up. Remove the belt and spin the pulley by hand. If you hear a light grinding sound or the pulley is stiff then the alternators bearings are worn. Take the alternator to an electrical repair shop for rebuilding. I usually pay around $50 as opposed to $100 or more from a parts store. Look up auto electrical repair in your Yellow pages. Older VW's are known for starter and alternator failures so finding a cheaper source for parts should help you save some money.

91 Ford Mustang what is common wiring problems and starting problem with the starter and heard in a pop under the hood on the driver side n smoke coming from drivers side under hood?

You did not mention what the status of the car was when this happened (VERY IMPORTANT... DO SO NEXT TIME). If you were attempting to start the engine when this happened, your starter may have failed. Starters occasionally shunt and cause this. Try replacing the starter AND starter solenoid. Also, verify that your battery connections are good, and that the battery wires did not have a meltdown. If they are burned, REPLACE THEM as well.

I have a 1996 dodge caravan that starts hard in cold weather!

Cold weather has an adverse affect on batteries. The clicking sound could be from the starter solenoid not receiving enough voltage to energize the starter motor. The engine being hesitant to start and run could indicate the need of new spark plugs, wires, etc.

91 jetta won't start ... what could be the problem? battery is good and electrical wiring seems to be fine.

I would check to see if you are getting spark to the plugs, could be a bad control module or a bad distributor rotor. Can you hear the fuel pump come on for a few seconds when you turn on the key? If the starter is not turning over, it could be the starter solenoid or the ignition switch is not sending any power to the small terminal on the solenoid.

Golf sometimes no power to starter motor

I would check the ignition switch. You can unplug the small wire at the starter, with a test light check and see if power is at the plug when you turn the key to the start postion. If there is power there, you may have a bad starter solenoid. I've had to replace a few on my VW, (86 Scirocco, 91 Jetta GLI)

2003 jetta gl manual trans-positive battery and ground starter cables have plenty of juice going to starter...but it grinds when i turn the it doesn't start at...

I presume you mean 'grinds when I turn the ignition..(to start)'.
If this is so, it's most likely the starter motor 'drive (overun) clutch is faulty.

Either replace the starter motor complete or replace the drive clutch assy on the original.
The latter should be cheaper (especially if you can source a new 'drive clutch' and fit it yourself).

1987 VW Jetta won't start. Starts occasionally when you jiggle the gear shift. Replaced the contact bridge and soon will be replacing neutral safety switch. If this doesn't get it started, what should I do...

I have an 87 Jetta also. The problem is basically that the electrical wiring throughout the car is getting brittle and the wires rub against metal and other items on the frames (sometimes sharp edges are involved. Once moisture gets under the wire insulation, the braided wiring begins to corrode and resistance to current flow increases over time. This has effected everything from the radio to the headlights in my car. Starting the car with the ignition switch got more and more difficult.
Then, I simply got a starter button from autozone (about 15 bucks), wired it with new 10 gauge wire directly to the starter and the battery and mounted the switch on the left side of the steering wheel on the dash (eerily there is a perfect mounting place for it). For the last 4 or 5 years, I just turn the key to the on position and push the starter button and it cranks reliably every time. Some day when I get time, I will run a new hot wire from the battery to the main fuse block under the dashboard. In the meantime, the car starts and runs great.
