Doo I need a new pump?

Mines factory and has the Mitsubishi logo on it also which I thought was very strange. As far as gravity feeding it. I live in New England and with a foot of snow on the ground and up to 6 more tonight. Fixing it short term isn't really feasible. I did get the new points kit and will try to install that later tonight. And hopefully get the bike back together and running like new again

well, got the pump all back together with the new points kit and hooked back into the bike, the pump still isn't working correctly, I'm hoping that maybe I screwed up the soldered connection, and if I try and re do it that it will fire up with no problems. There is fuel up until the pump, and it was cranking without problems. Does anybody have an idea of what else could be a problem with the pump?

Make sure you have good ground and power while cranking at the fuel pump connector. If so check the points switch on the pump and make sure it's working while cranking also or it might be a bad connection there. If the points are switching back & forth it should start pumping fuel unless something else is damaged. It's been awhile since I had mine apart but I think there is a diaphragm inside that moves in/out to pump the fuel.

It means you possibly have no power at the pump.
If you can, hook it up gravity fed for a bit and get it fired up.
Take a multimeter and check for battery voltage at the connector.
If it's showing voltage take off the end cap from the fuel pump and clean/sand all the points of contact where the wires come into it
If it's not showing voltage then follow the wires back through the wiring harness.
Check out the fuel pump relay, if everything is okay there, then it's possible you have a pinched wire causing a short or open circuit

You will need either a testlight, or a multimeter from this point forward. you can get one for $20, but i believe no matter what route you take you will need one.
If voltage is shown then it's the fuel pump side
- you will need to remove your seat and tank
- follow the wire from the fuel pump to the harness, you should find a small 2wire connector. Unclip it
- Take your digital multimeter (make sure it is set properly. 20V DC)and attach one probe to either wire coming out. (harness end of the connector not the fuel pump side).
- turn on bike to on position and press the starter button.. you should see battery voltage on the multimeter
