Question about 1987 Volkswagen Cabriolet

Car will start but as soon as key is released it will die just as if the key was turned off, It was running one evening and next morning would not run. Any ideas where to start? I Had put new spark plugs, rotor & cap in less than 100 mi before this started up

    Hello, I checked the Ign switch & it seems to be fine, It is a 4 pole switch with one hot all the time, when switch is in run position 2 others are hot & when in start position the 4th is hot. Would this indicate the switch is ok?

    Hello, Thanks for the suggestions, here is what I discovered since my last post. The fuel pump relay was bad, so I replaced it, I noticed on the diagram that a wire goes from the fuel pump relay to the coil so I thought problem fixed, Not so! It runs better when in start position but still shuts down immediatly. What does the wire from fuel pump relay to ign coil do? The man I got the relay from told me that those cars were bad to leak at the windshield & get water into the relay's & fuse box & that was exactly what had happened. May have caused some more problems.



    I am not real clear on the comments on the ignition, but will continue to check it out. Seems to me with a simple 4 pole switch with one hot wire going in & 2 more hot in the run position & the 4th hot in the start position the problem would be beyond the switch. I can pull the plug back far enough to get readings off of each pole. Let me try to illustrate what I have found.



    POLE #1 Hot wire coming into switch, this is hot even with switch in off position



    POLE #2 With switch in on or run position it is Hot.



    POLE #3 With switch in on or run it is hot, when switch is in start & starter is turning over current goes out but come back as soon as switch is released to run



    POLE #4 Is hot only while in start position



    Thanks for help

In an older car,there are more worn parts, I'm going to fire off a check list and action items.

Please compare to your service and see when the parts was replaced.

I'm going to start off with the easy one first.



When the key is at the ON position,do you see the check engine light,seat belt........radio on?




======
Is the electrical portion of ign. lock every changed?

Use compress air and blow out any dust behind the key lock.

Check for loose connector and corrosion on the connector,

Check hold down screw.
======

======
There is one wire to the switch for ign. on. This wire is probably broken or there is problem inside the ign. switch.
======

I would replace the ign. switch ASAP.

New time you start up the car in the morning,take some paper towel with you and wipe the electrical part of the ign. switch dry before starting.


A switch does not last forever.

I strongly recommend you to change the ign, switch because worn electrical item can catch on fire.


Please do a clean up,check the connectors and wires behind the key lock.


Good luck.

    My bet is still on the electronic part of the ign. switch.


    Make sure the connector is clean. You will need to go way down the dashboard to do this.




    Please make a count of click/turn on the lock until it reach the ON position.

    Do the same on the electronic ign. switch.


    You should get 12V power at the post/wire when you are ON position.


    I will look up some pictures for you later.

    I would spend 1-2 hours carefully remove the fuse box and inspect the underside of the fuse box.


    My first company was in a small flood. It ran fine until the headlight stop working. It took the shop 9 hours to found the short behind the fuse box.


    I recommend you to inspect the fuse box first.


    Check for voltage out put on the fuel pump relay /////at start up or //// right after the engine die.


    I want to rule out bad/intermittent power supply to the fuel pump relay.

Hello, and welcome to FixYa. Please allow me to assist you. It looks to me like you need a new ignition switch. The way you describe your situation leads me to believe that the internal electrical contacts are not making contact in the 'run' position. I'll bet that a new ignition switch fixes you up.

Regards,

Toyota Ed

Starts but wont run


Some automobiles have a resistor in the coil circuit to reduce the voltage when the car is running. GM put it inside the starter solonoid for earlier cars. Chrysler put it on the firewall. When it goes bad the engine will start running when you crank it but it will die as soon as you release the key from the start position.

try rapping the mass air flow box located between the air filter box and throttle body assembly. if it affects running it's probably bad. VERY common problem. so common there may be a replacement chip for the inside of the computer that bypasses it altogether using the map sensor instead.

My car wont stay running


Does the engine die as soon as you release the key, or does it run for a couple of seconds after you release the key and then die? If it dies as soon as you release the key, try holding the key for a few seconds and see if it will stay running as long as you are holding the key (the starter will make a grinding sound while holding the key but won't hurt anything). If it stays running while you hold the key then dies when you release it, that indicates that the ignition switch is bad.
