SolvedEngine runs but won't start
Volkswagen Jetta 2001 143 miles
Hope someone can help me. I own an automatic Jetta 2001 and it was working properly until suddenly, one day, it wouldn't start again. The engine runs but there is no way it can be started. The fuel pump's pressure has been checked, the coil replaced as there were no sparks in the spark plugs, but the problem is still there. All fuses are alright as well as the crankshaft's sensor. The acceleration body has been cleaned and the battery replaced. Can the stereo have something to do? Because it is indicating SAFE 0000, meaning that the car is blocked? Can someone please tell me what to do?

After many attempts at trying to solve the same problem you are now having with my Jetta 2001, one day I found out that the temperature's sensor, through which the cooling liquid runs, had oil in its exterior. It was dirty due to a previous tuning, so I removed the connector to clean it and the failure disappeared. I really don't know how this can affect the starting, but I cleaned certainly deeply that connector, which has 4 pins, and the vehicle started as if nothing had happened. I then bought the sensor and the problem was finally solved.

Thank you, siller for reading and sharing your experience. After trying different things, I myself removed the crankshaft's sensor, took it to a good electrician and he said it was not working properly. I then bought a new one, installed it and it finally started.
