    I'm not sure of the year but it has been sitting a while(it was my uncles) but I put a good battery in it and I was trying to start it. While he had it ,he put a push button start on it. So I turn the key and it's loose and turns all of the way and I hear the fuel pump come on but when I press the button ... Nothing no sound or anything but I know it's not the battery because the blinkers and stuff work. Do y'all have any tips to get it to turn over? Any help is appreciated!

    Maybe the switch has burnt contacts.
    Try a new switch or jumper wire
    across the switch terminals.

    On the back of the starter switch should be two terminals. Get a small length wire or even a screwdriver and jump across the terminals. Wear safety glasses they may be a small amount of sparks. It's 12 volt system it won't shock you.

    Jump the terminals quickly just long enough to bump the starter over. If this doesn't work there may not be 12 volt + going to the switch. Check for 12 volt+ with a cheap 12 volt test light on the starter switch terminals.

    Could be the starter solenoid also.
