Question about 1987 Volkswagen Cabriolet

1 Answer

I have an 87 VW Cabriolet that totally stalled out on me and smoke that smelled like gunpowder was coming from under the dash. Sounded like the car was not getting fuel. I replaced the #5 circuit...which was fried and the car started up. I drove it around my block with no problem. About an hour later, I went back out and the car will not turnover to start. I am having trouble locating the relay...and the part is expensive...any way of trouble shooting for an amateur to see if it is the relay or the fuel pump?

Sounds like you have a positive wire grounding out on your vehicle.  Look around under the dash for any tell tell signs of arcing to ensure you do not have a bare wire somewhere.

As far as the Fuel pump and relay...what I do is jump the fat, flat, wide terminals where you unplug the relay with a fused jumper wire. ( basically a wire the has 2 male blade connectors on each end with a fuseable link in-line betweem them)

\
With your battery connected and the key off you should hear a loud humming or buzzing sound when you jump those wide terminals in the #2 slot of your fuse box.
If you get the noise, it's the relay, if no noise,make sure you are jumping the correct terminals and assume the pump is bad.  $100 repair either way if you go the the auto parts store.
Hope this helps!

I have a 87 Chevy silverado when I turn the key over it clicks then smoke comes from under the dash on the passenger side is it a problem with starter


No....You have something else going on here and I don't know where to start exactly. You will have to have someone else observe where the smoke is coming from but it should low voltage. I would have a pro look at this one.

1990 VW Cabriolet Gas Smell and humming from gas cap...The smell and sound happens more frequently on warm/hot days. Gas cap seal has been replaced, but still having problems.


The humming noise is coming from the fuel pump.  Its possible its getting ready to fail.  These start making noise when they are going bad.  The smell can be coming from bad gas cap not sealing up fuel tank properly and or a fuel pump/sending unit seal.  You can pull the back seat bottom out easy enough by removing 2 5mm alan screws that secure it to the floor.  Remove the seat bottom buy pulling out and remove black cover under seat bottom that has 3 philips screws.  you may smell fuel more promanently here.
