Is there suppose to be current running through the plug for the coil?

I have a 2001 VW Jetta and the other day we were checking for a short. I hooked up a jumper wire to the neutral safety switch to see if there was current going through it. The car ran fine prior to this test, and it was started once after this test. Now the car only cranks. There is no fire to the spark plugs. I tried to check the current running through the plug to the coil and I have nothing. Any suggestions?

    Car is turning over fine, just no fire going to the plugs.Battery has close to 13 V

    Batteries actually have more than 12 volts so that's normal. 12.7 comes to mind. Good luck.

Do you have voltage to the coil? If so the coil probably bad. A likely scenario based on what you've said. If you have voltage to the coil then keep tracing back.

SOURCE: 85 ranger, engine cranks but won't start.

Sounds more like an electrical problem.First I'd check the battery voltage, should be at least 13. It shouldn't drop much below 11 when you crank the engine and it should bounce back when you stop. Make sure your connections are good especially to the coil,wires aren't frayed or loose on connectors. There should be a ground from the body to the motor. Is it still thereand making good contact? If I'm not mistaken the coil should ground to the motor, make sure it has good contact as well. Also double check your connections at the starter to make sure they are clean and tight. Loose connections can draw extra power and could draw enough extra power to kill the coil. Hope this helps.

Take off the distributor cap. Check the star wheel that is splined to the distributor shaft that the pick-up coil uses. Make sure this wheel is not loose on the distributor shaft. It is right above the pick-up. If it is loose, replace the distributor. This is a common problem. If it needs one, all the part stores stock the distributor.

There may be no injector pulse if the computor does not see a RPM signal.
There will be no spark if the ignition module does not see a dist pulse from the dist pickup.......a RPM signal.
Because you do not have both ......I would suggest to check/change the dist pick up.
Follow the wires from the ignition module inside the dist to the pickup which is also inside the dist.
If it is just a bad dist pickup....keep all your old parts as good spares.
Also...is the dist turning? to provide a RPM signal?
You will have to remove the dist to change the pick-up.....mark your timing locations......"rotor position" and "dist body location"before removal.
A quick test before installing the "repaired dist" .....plug it in the the truck wiring and turn on the key....DO NOT CRANK THE ENGINE OR YOU WILL LOSE YOUR DIST ROTOR CORRECT POSITION......as you spin the dist by hand .....the injectors should spray.

I have a 2008 volkswagen jetta that has 9500 miles on it. this morning there is a yellow light on that resembles an engine? I think it is suppose to be an outline of an engine


Engine trouble or service light. Could just be wanting an oil change, maybe something more. Is it running OK? Check owners manual for details about the light. You are probably still under warranty anyway, check with VW dealer. It may not cost you anything to fix.

2001 Jetta VR6, 76k miles. Transmission fluid leaking, occasional short-term power loss. Have gotten the impression from many that newer VWs need (expensive) VW experts. Can I take this to a friend who...


Auto or Std trans??

If auto here's the issue...

Keep in mind Auto transmissions don't like to be run dry.

Also keep in mind that the 01M Automatic you most likely have retails for like $4000 just for the unit, not installation.

The corner trans guy can't rebuild the trans. This is a special unit

Just to check the fluid-

Hook up a Laptop with Vag.Com software installed.

Start the car and go into the transmissions data blocks and go to block 005, this will display fluid temp.

-ATF temperature not above approx. 30C (86F)
-Vehicle level
-Selector lever in "P"
-If ATF is below 30C (86F) bring the ATF up to test temperature.
Test temperature: 35C to 45 (95 to 113F)
-Remove ATF level plug from oil pan.

CHECKING PHYSICAL QUANTITY

If ATF drips out of hole:
ATF need not be topped up.
-Install new seal on plug and tighten to 15 Nm11 ft lb).
ATF check is completed.

If ATF does not drip out
-Remove plug from filler line.
-Fill with VW ATF (G 052 162 A2) until ATF runs out of level hole
-Install new seal on plug and tighten to 15 Nm (11 ft lb).
ATF check is completed.

CAUTION!
Too little or too much ATF will adversely affect transmission function.

My VW 01 T1.8 vibrates when i increase speed


It sounds like either bad plugs, wires, or timing. Also check for vacuum leaks. With the engine running, wiggle all your vacuum hoses around, and listen for a hissing. Also check intake manifold bolts for tightness. Coils could also be faulty. Fuel filter could be partly clogged.

Battery drain


My wife's 2001 Jetta TDI had the same problem. First we changed the battery. (It was just about due anyway) No change. We then traced the power drain to the in-trunk mounted CD changer. This was an aftermarket CD changer but we went to the same source that the VW dealership uses. Of course one blames the other. The CD changer was even replaced with no change. If we are not using the car for long trips we unplug the CD changer and no more dead battery! Neither the VW dealer nor the AV installer could give us a good working solution to this problem.
