95 Jetta Starting problems by eepower

My 95 Jetta with a VR6 will not start. The engine turns over. Fuel is getting to the injectors. The spark is good at the plugs. It seems to want to start but won't.
Any thought?

Is it normal for the voltage on all on the fuel injectors to be at 12 volts when the key is in the accessory position before starting the car?

I beleive the answer is YES... +12 on all injectors is to prepare them for action. The engine computer pulls the other leg of the circuit to ground when it wants to squirt fuel.
 
This is how most engine-computers work when they need to control an external load. The output signals are just pulled to ground to turn things "on".

I am new to this forum so please bear with me. My sons girlfriend bought the above vehicle from a corner lot dealership.
i know first mistake however she is only 19 and on her own so she is doing the best she can. Had overheating problem replaced theromstat afterwards bubbling from resouvior. torn down head checked out found two cracks in turbo replaced, water pump replaced, all belts replaced. all good for test run and idling. They went to leave got about 1 block heated up again.
found raditor clogged. My son remember he put white grease on engine to keep no rust from forming whiles waiting on parts to come in. then cleaned out raditor. when to restart car started then stalled out. will not start now. it does crank. there is also a light on dash now that is a traingle with a car inside with a key symbol under it. We are having a difficult time finding someone with volkswagen knowledge. before they started this adventure they called vw repair shop they were told 3 thousand to replace the water pump needless to say this young lady does not have that kinda of money and neither do i to lend it to her. Now we are lost as to why this will not start. any help would greatly be appreicated. I found this site while looking up information for them. I am hoping someone out there can relieve the frustration they are feeling now...

Sounds like the immobolizer is keeping engine from running.
 
There is a chip in the key which is "read" by the ring around ignition-switch. If this chip is not matched to the dashbaord/ECU, the engine will start but immedeatly stall out. The light on dash that is a traingle with a car inside with a key symbol under it is also an indicator of immobolizer.
 
Is this the ORIGINAL key that is intended for this vehicle?
 
Here is some info about immobolizer system.

yes it is the orginal key. Now it has been raining here for the past week could that also be a factor by what i am reading in the other people commments.
 
thanks for information will keep you updated
 
Again thanks

Hello bpeebles,
my son thinks he has somewhat found hopefully the problem. One of the fuses #37
was blown Its the one with the picture of a book on the diagram. put new fuse in
that fuse blew before even trying to start the car. Figuring its a ground but don't know where to start to look. Oh by the way the little symbol disappeared. And I did find out the key she has is the only one, and the dealership never gave her the black tag or they didn't have it to give her.

it's been at the VW garage where they have now logged 15 hous of diagnostic time with no results.
when it first occured there was a strong electical burning smell?? I would have assumed the VW tech's would have figured it out by now. with no luck I'm hoping someone out there may have come across this unique problem - thanks
