VW Jetta first of the new body style. Had some chances in behavior in the interstate and difficulty starting last winter figured it was the cold but it always turned over and started after a while. Then one day it didn’t and a few guys at work helped me roll start it. Finally it gave up on me while driving and couldn’t get it to start up again. So I replaces the fuel pump as recommended and a fuel line that was leaking everything seemed good also replaced the filter and a few radiator and coolant system leeks that happened before. So with the new pump replaced I started it right up and it ran seemingly fine then I drove it down the road and got out to look for someone and left it running and when I got back it had shut off as of right now I am writing this with it running and it died before I could finish I heard a little click inside the dash before it shut off and it doesn’t want to start again. Seems like I wait and it starts up with a day of waiting. Check engine light has always been on for the crank shaft position sensor and it runs pretty well when it is running. Where do I go from here to diagnose this problem because the pump was simple for me someone with limited mechanical knowledge. Do I need to start trying to get to the injectors or what fuel related sensors do I need to look into. Also I haven’t seen the fans kick on for the radiator in quite a while co it be a sensor tied to that causing it to stall on me?

Hello,

I would say to replace the crankshaft sensor which will cause the problems you are describing. Here is a guide that will walk you through the steps with diagrams below so you can fix your car. They call it an engine speed sensor.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

So after more trouble shooting my mechanically inclined friend helped me find a fried looking fuse box under the hood and swapped that out and nothing changed. Then I finally got the right sensor in a day or so ago and swapped it out tonight. Now my car won’t even start. I have the cam sensor and waiting for my friend to help with hat cause it’s behind the timing belt. But now there is a new cam plugged in and it’s now the car won’t even turn on. I swapped it at night and I’m going to double check in the morning in sufficient light but it was pretty simple. Also when I unplugged the old sensor I undid both battery terminals and when I put the cables back on my alarm was set and my key doesn’t turn it off and the fob doesn’t work. So I redid the battery cables to turn the alarm and that seemed to do the trick, but I want to disable the alarm system so I can lock my door without engaging the alarm. Anybody have any idea where to find those specks for disabling the alarm system?

You cant disable the system, when you crank the engine over is the security light flashing? If so let use this guide to reset the system:

Well I guess I must’ve done something wrong cause she is dead. So I put the new sensor in and got it right and she started and was running well all day. Then right after I paid my insurance and was gonna pull outta the parking lot she died. I revved it to life but died again and would not start once every one had passed me I backed back in to the parking lot. Turned the key one more time and it sorta started but it sputtered never reaching idle. Timing belt? Now it just won’t start period.

It could be the timing belt but if you can please shoot a quick video with your phone so we can see what's going on, that would be great. You can upload it here with your response. I can tell was is wrong by seeing the engine crank over.
