Please help! Injectors aren’t spraying. My fuel pump is cutting on, it’s not my battery, not the kickstand switch! All I did was changed my quick shifter to gp and changed my battery to a lighter battery. Wouldn’t start. I replaced my battery and put the old one back in which was perfectly fine and hooked everything back up. I now took the tank off, cleaned it all completely out and checked my fuel pump. Also bought new spark plugs just Incase it was them. It is turning over but not firing.
