The bike won't illuminate the N on your dash or start when it is in neutral without the clutch pulled in.

How do i by pass the neutral safety switch in a dodge neon 2003


If you mean you want to start the car without the switch interfering, yes, you can do that by cutting the tan wire from the starter relay and grounding it to the chassis. This will allow the engine to start in any gear. However, the switch does a lot more that neutral safety. It tells the pcm what gear you want to choose. So, if the switch is bad, it could give the pcm bad data about your selection. Bottom line is, the car should start (please have your foot on the brake when you try), but the transmission may not work as expected.

Why doesn't engine turn over?


Check the battery.Is it charged?Also does the neutral light go on?
If not check the neutral switch.
The neutral switch is behind the engine case near the rear shock and has one wire. Make sure the bike is in neutral or on stands. Remove the one wire and put it to earth/chassis/ground (somewhere metal on the bike). The neutral light should come on and you should be able to start the bike if that was the problem.
