Honda foreman 2000 450 won't start but fires sometimes with electric start when letting off button but does nothing with the pull start.help

it seems like your ignition switch may not be removing the ground while in the starting position try removing the ground wire from key switch if it turns over and start with key replace switch assy.

Check the connections at the computer.

Hi Donnie,
Start with the basics, Good electrical connections, good grounds, good fuses (test them! they can look good but still be bad) then start looking at the circuit for the shifter. If you can't find a schematic then you may have to take some stuff apart to get to the electrical end of things. Check the switch for the shifter.. If you need some more let me know

Look for broken wires on bottem right side of engine on park /neutral safety switch wires pulled off or broke

This may be of some help

Check schematics for a hot start side and if it is chase down that wire to see if the line for a hot start is really there? Is crank speed fast or slow. My bike if it isn't above 400 Romo's I have nothing. A dead stick,the computer will not help me, I am on my own.

try spaying wd40 into the switch assembly with the starter button. leave it a few mins and start it up.

Check the starter switch (button) .
