Can someone please tell me what to do?
CommentMany failures Solved
Volkswagen Jetta 1999 135000 miles
The first failure in my car appeared from one day to the other. It was working perfectly one night, but the following morning it wouldn't start. There was some engine work but I could not start driving it. It seemed as though there was a fuel deficit, but it had been refuelled the day before. I checked the fuel pump, and surprisingly found out there was no sparking, so I logically thought the problem was with the coil. I changed it but it kept doing the same thing.

The same happened to me and the problem is in the distributor.

I can start it by spraying starting fluid into the air intake.
I have replaced the Fuel pump, fuel injectors, Fuel Relay 409 (under the steering wheel), the ECM, and crankshaft sensor. Crank position sensor. I am now lost why this vehicle won't start.

The fuse box imagines on this website helped alot. Once I installed all the the parts. I noticed that the fuses on the side of the drivers panel were missing some so I checked this websites fuse diagram and noticed I didn't have one for the Fuel injectors. Once I added it car started right up.

CommentFuel pump relay
Volkswagen Jetta 2005 4dr. Sedan 2.5L 198000 miles
Where is the location of the fuel pump relay. Many diagrams show under the drivers side dash n some show engine location drivers side relay 3 but when I see the relay part number and location area they don’t match with the holes in the fuse panel. I’m so confused.

Volkswagen Jetta 2012 Sedan 5000 miles
Since buying my jetta i have had nothing but problems, one of the worst being a split in the top of the fuel tank my mechanic tells me from what he can see he believes its a manufacturing problem and to add to it the original fuel filter was still on the car at a 100,000 kms has anybody else had problems with their fuel tank? As vw tell us not their problem but cant understand how i could possible do that kinda damage to the TOP of a fuel tank thanks in advance
