I had to replace the fuel pump gasket on my 600 and when I reinstalled the tank and turned on the key I got nothing. The fuel pump light comes on for about 3 seconds and then goes out just like it's priming. It won't crank either. I don't see what I could have done to screw it up since there's only 1 electrical plug and thew 2 fuel lines. The only thing I did different was that I applied some gasket sealer to the fuel pump gasket. Any ideas? Thanks for any help. ???
