2006 JD Gator 620i w/ Kawasaki FD 620 engine. I’m having an issue with no spark at the plugs. I get 9.5 volts to the coils in the acc/prestart key position and 12.55 at the battery but no spark. Any ideas? Second issue is I’m finding $250 for the fuel pump AM136232 and no longer made. Any ideas on an equivalent? Thanks.
