I don't see how any light or accessory power circuit would affect the fuel pump but when a light bulb shorts out the arc to ground can cause a lot of problems on unrelated circuits. Unfortunately I can't help much from what you've posted especially since you say all relays and fuses are good..i have a vrscb i crushed the rear light bulb by accident and now the bike turns over but want start i cant hear the fuel pump. All relays and fuses are good . Any ideas how to fix?????????
