Question about Cars & Trucks
When i attempt to start car all power is cut off from batt as if the batt was dead no horn no lights
Check that the battery posts and terminals are shiny clean and tight. Have a load test done on the battery to check for a dead cell.

plz check the following and update me
1. Fuel (To be exact proper air/fuel ratio, normally it is about 14/1)
2. Spark (in appropriate moment)
3. Proper timing (the valves should open and close only in appropriate time)
4. Compression in the cylinders (Normal compression is 120 - 170 psi. The engine won't start if the compression is lower than 70 - 80 psi.)

Battery is in trunk compartment. Must be positioned exactly and locked down. Not easy to do and keep in position unless using BMW battery. There is a slight size difference (BMW wants to sell their batteries - at inflated price.) Save yourself the headaches and get BMW battery. In the meantime, just move your battery position a little bit until trunk light comes on. Car will start if trunk light is on - unless the problem is really something else. Hope this helps. Let me know.

the jetta has a faulty alarm system from the factory i have been working on one in my shop. the alarm moddule is inside the dash behind the light switch and has a 10 pin connector and a 6 pin connector. this can be bypassed if you disconnect both connectors and jump the two large wire on the 6 pin connectors, these wires operate your starter. the car will start and run but your alarm will no longer be active. the door locks and everthing else will still work. the only issue i am having is the factory radio isn't working because it is controlled by the alarm. but worse case scenario i can use an aftermarket radio if need be.

It could be a defective ignition switch as well (it has a disabling circuit) thinking the vehicle is stolen. The dealer has the equipment to see if is throwing a code for that.
