2001 new beetle will not start. I have replaced the starter and two days later same problem. Is there a way to test the neutral kill switch and the alarm system? Should I pull the wiring in the steering column? One site said running all the power will damage the wire cluster in the column.

Your alternator is not for 2001 infinit i30 that's the cause of killing your starter.

Dirty battery posts...(loose) or locked starter...sometimes you can tap the starter with a hammer to make it work one time to confirm...Hope this helps.

May be ab bad starter solenoid, or corroded/loose connection at starter, or (ground). Could also be a bad ignition switch. Start from the load; the starter. Test for 12V at starter, OK. Connect short wire from starter and touch sylenoid connection..

If you put battery voltage to the starter solenoid &
it works & the starter works,then the solenoid control
circuit has issues

Fuse,ignition switch,neutral safety switch,clutch sw
& such, depending on what the car has

You could try switching relays but doubt that is an issue

Test/Service/Replace

The circuit on newer cars with automatic transmissions has a neutral safety, or neutral start switch installed between the ignition switch and the starter. The ignition switch cannot operate the starter motor unless the transmission is in park or neutral.
Late model vehicles with manual transmissions have a starter/clutch interlock switch that requires the clutch to be depressed to the floor.
Neutral Safety Switch
Normal operations of a neutral safety switch provides a quick check for the adjustment of the gear selector linkage.

• To do this, move the selector slowly until it clicks into the PARK position.
• Turn the ignition key to the START position.
• If the starter operates, the PARK position is correct.
• After checking the PARK position, move the lever slowly toward the NEUTRAL position until the lever drops at the end of the NEUTRAL stop in the selector gate.
• If the starter also operates at this point, the gearshift linkage is properly adjusted.
• This quick test also tests the adjustment of the neutral safety switch.
• If the engine does not start in either or both of these positions, the neutral safety switch or the gear selector linkage needs adjustment or repair.

CAUTION
Since you must work under the vehicle to adjust most shift linkages make sure you properly raise and support the vehicle before working under it. Also, wear safety glasses or goggles while working under the vehicle.
A voltmeter can be used to check the switch for voltage when the ignition key is turned to the START position with the shift lever in PARK or NEUTRAL. If there is no voltage, the switch should be adjusted or replaced.

could have faulty starter or starter solenoid.hook test light make you a test light with longer wires and 12 volt bulb with socket go junk yard find good bulb with socket.hook test light to starter and see if test light lights up if so your starter or starter solenoid has a open winding. if test light dont light up could have blowed fuse to transmission neutral switch or neutral switch could be bad.try to start vechicle in neutral if vechicle starts your transmission neutral switch out of adjustment or neutral switch faulty check make sure wires going to neutral switch is damaged.

It sounds like a fault in the starter circuit. It could be a defective neutral safety switch, starter solenoid, or possible a defective ignition switch but I doubt it. Can you hear the starter solenoid??? I'm willing to bet the problem is either with starter relay, neutral safety switch, or starter solenoid.

You will need to replace the Neutral Safety switch on the transmission.

try bridging the wires on the starter motor with a start button.
that or replace the ifnition switch.
if you bridge and the starter doesnt turn over its a bad starter
if it does its a bar ignition switch.
lmk if this helped
