2007 VW Jetta MK5 no start, no spark, cranks no turnover

Does your engine light come on when key is in position 2? Can you pull codes? Check for power at ignition coil plug in, not spark plugs. If you have power at plug and no spark, bad coils. If no power you can look to CPS or ECU. Multimeter helps in this area

engine light is not coming on.

Finally got to the bottom of this issue. After months of failed attempts, replacing fuses, checking connections, even having the ECM tested at a facility that rebuilds/flashes them to no avail. It finally was determined that the ECM was not getting power from the fuse box/ power supply. The ECM is located in the windshield wiper well under the windshield. The constant movement of the wiper arm running against the wiring harness caused an internal break in the supply wire that was not visible when inspected externally. Replacing the supply wire solved the problem.

Immobilize issue, solved mine. 15 minutes keys on position same time connect some jumper cables battery must remain certain Amps it will fire up boys . 2.nd tricks disconnect battery positive and negative also disconnect another red wire from the negative cable ,exactly 15 seconds touch each other then reconnect everything back will fire up
