Check engine light came on a 2007 1100 vstar

What does the battery voltage drop to when you are hitting the starter button? Are you attempting to use a jumper battery as the "good" battery?

Question edited for clarity.
Question moved to model category.

Did you check the neutral light, bulb?

the other possibility is the Neutral Switch.

13 is intake pressure sensor problem - check the intake, make sure wires are attached & all closed up properly before considering sensor replacement.

THis shows working around the intake:

oil lights work off pressure , check wire connection and oil level coz if there isnt enough oil in the engine it can pump oil around and end up with not enough in the sump ! whats the quality of the oil , when was it last replaced ?

Check the voltage across the battery with the engine running , should be around 13.5v


Vibration is another cause of bulb failure

Take the bike to the shop to diagnose, more than likely it is a Throttle Position Sensor. It could also be a blocked fuel filter starving the engine. Only the mechanic can obtain the codes and point you in the irght direction.

Hi and welcome to FixYa,

Initially, have you checked the neutral position switch or its wiring? In most versions, the wire would be skyblue in color. Additionally, checked the diode. Alternately, if the turn signal lights indicator or the engine indicator lights are likewise not working, then check the signal fuse.

Good luck and thank you for using FixYa.

Twisted bolts on the starter are never a good thing. There is also a one-way starter clutch on the crank behind the flywheel that can be damaged. If it engages intermittently, it's on its way out. Both the starter and starter clutch are prone to failure on VStars... and neither are cheap to fix. Hopefully your bike is still under warranty.
