How to replace the ignition switch or troubleshoot (Honda, Acura)

 

see now its not getting anypower at all... but would that switch cause it to die while its running?

 

You could be losing voltage on IG1 on this diagram.
How the Main Relay works
Are you running a 255lph walbro or bigger? If Yes you might have to install a relay with 10 gauge wire as I bet your main relay is getting Hot. This could be THE problem.
Pm for how to wire in a additional relay.
