How to fix no power to fuel pump on 2005 Polaris 700 Twin EFI and same thing applies to other models as well. First disconnect electrical connector to fuel pump and make sure fuel pump runs when you apply 12 volts to the red terminal and the brown with brown being negative. Then reconnect plug if it runs. A lot of polaris electrical problems are related to poor ground connections as in this case. The EFI ECM was also bad in this model so be mindful that ECMs are notorious for being bad as well.
