Welcome to Just Answer!!!

Does it stay running if you jump start it?? It is can bus wired
Customer: replied 3 years ago.

it wont start buy jumpping either, it has a good ground and i reconnected the starter,and fuse link wires to the + post on the battery

Expert:  vwtech0405 replied 3 years ago.
If you have good battery voltage then your next step will be to check to see if you have power going to the one pin connector on the starter solenoid do you have power there?? if so how much??
Customer: replied 3 years ago.
16.75V with the charger on w/0 14.5V
Expert:  vwtech0405 replied 3 years ago.
Thats at the one pin connector on the starter solenoid while cranking ????
Customer: replied 3 years ago.

Expert:  vwtech0405 replied 3 years ago.
No not this one there is a one pin connector on the starter solenoid disconnect the connector and crank the vehicle and tell me how much you voltage you have there??
Customer: replied 3 years ago.

Expert:  vwtech0405 replied 3 years ago.
Ok you are getting power but it may not be enough are you sure this battery i good you need to have a good amount of cold cranking amps??
Customer: replied 3 years ago.
the battery has 13. 4 V @ 750 cca, but it may have a dead cell its a newer battery that was purchased 9 /10
Expert:  vwtech0405 replied 3 years ago.
What exactly happened when the radio was installed??
Customer: replied 3 years ago.
owners used a off brand harness that didn;t have a 12v acc wire, so i dropped the dash panel and tested the igination harness for 12 acc and t tapped to the acc wire , but before that the radio would stay on and drain the battery. so i removed my t-tap and now the 409 and 377 relays under the dash buzz really loud, and not start
Expert:  vwtech0405 replied 3 years ago.
That is the wiper relay and the fuel pump relay does the vehicle crank at all???
Customer: replied 3 years ago.
no , sometimes i can hear the clicking of the starter and sometimes nothing like theres no ground, but the ground is good, the doorlocks and windows wont work at all now, i have read that jettas have electrical issues
Expert:  vwtech0405 replied 3 years ago.
Ok heres what you will need to check you will need to remove the steering column trims and check to see that the electrical part of the ignition switch is good and sending power to the starter solenoid, you will also need to make sure the comfort control module located behind the steering column is not shorted out but you will need a vw specific scan tool to check the module. i hope this helps.
