I just got a 1987 trx350d Foreman. When I turn the ignition on the fuel pump runs for maybe 2 seconds and shuts off. If I jump it to another straight 12v source if runs fine but on the bike it stops after 2 seconds. I am a complete noob here so if its something simple be gentle with me lol.

I can't remember if those had a fuel pump relay or if they had some kind of control unit to operate the fuel pump, but I would say the problem is with one of those. If the carb or fuel pump has a return line back to the tank, you might be able to wire it up to a keyed 12V power source, bypassing the control unit. Shadetree has just finished restoring one of those 350's. He might be able to help you more with this problem when he checks in.
