Engine runs but won't start 
Solved
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?

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.

The car's fans do not start working and thus the vehicle overheats.

No because he says it cranks over. So it can’t be the starter. It can be so many things. We need more details.

No dash lights, radio works, no wipers, windows, lights front and back (I do have daytime lights! Have blinker and break lights) cooling fans, a/c stopped working, drained it all out, put a tiny bit in and it was almost in the red, now in the red days later 🙄, a/c compressor not engaging…. Got some codes saying blown fuse (probably relay) no interior lights either not even the map lights work. Cooling fan and AC fan will not turn on car will overheat if standing still.

You might want to check the fuel pump or the belt because that can be the culprit and also check the starter fuse

CommentCar not starting
Volkswagen Jetta 2007 2.5 Wolfsburg edition 189000 miles
The car has been sitting for 8 months bought it for a very good price. I have good fuel pressure 35 , I have fire to all the coils ,plugs look fine, all fuses look good, but nothing just turns over seems like no fire or fuel. What should I do next? Also it had a po721 service code which I knew about I need to replace the output shaft speed sensor. No other codes

Volkswagen Jetta 2006 tdi 1.9 l automatic 144000 miles
I have a 2006 vw jetta tdi automatic, before it failed completly when i turned the key it would crank slowley a few times and then normally and start. Battery is new now. Starter has been replaced and the replacement tested and working. I witnessed it spinning in the test. When I turn the key it will not engage the starter or turn over. The lights do not dim and everything else seems to work ok. Any suggestion on what to try next?

Many 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. I then checked relays, fuses and that there was electrical current reaching the coil and everything was ok. The crankshaft's senso… Read complete

The same happened to me and the problem is in the distributor.
I've changed the distributor and it seems as though the problem has been solved. At least for the past two days it has been working perfectly. Thank you very much!
CommentStalls Solved
Volkswagen Jetta 2001 55000 miles
After driving for 20-25 miles, the engine stalls and it won't start again. Only after 4 or 5 hours the car will start again as if nothing had happened. After the same distance, it stalls once more and this happens time after time. It seems as though the engine was suddenly blocked. A new coil was installed but the problem is still there. I would appreciate anyone's help. Thank you.

Hi, you should check the state of the relay number 409, as well as the crankshaft's sensor. You should also verify that the new coil is working properly.
Best answer (according to Eph)
Your problem must be the crankshaft's sensor, located behind the oil's filter.
Comment2021 vw jetta 1.4 tfsi No cranking
Volkswagen Jetta 2021 1.4 tsfi 63000 miles
Doesn't crank. All the fuses are good. Battery is good 12.6 volt. No cranking at all. I hooked up the ECU from another jetta, same result. Looks like whether immobilizer issue, or ignition switch, or ground wire.

Sounds like MAP sensor is giving your car problems.
CommentNo Crank, No Start. Been troubleshooting the starter, starter relay.
Volkswagen Jetta 2007 4dr 2.5 SE 140000 miles
Car has good battery, 12.6 vdc with car off. When turning the key to the start position I hear what sounds like a single relay in the dash click. Sounds like its coming from the relay panel left of steering wheel. The 2007 jetta 2.5 SE is my wifes car & has seen better days. She drove the grandkids to school in the morning a week ago & went to leave a few hours later & no start. I've forgotten how to troubleshoot. Its been awhile. Update. I'm not getting power at the starter
