04 no current to fuel pum
Thanks for your reply; It is a Polaris Sportsman. I talked with a mechanic this evening and now believe the problem is most likely the fuel pump. According to the information I gathered the fuel pump must have a "closed circuit to work, thus if the pump is bad there would not be current available in the wire. I'm not a certified mechanic, just a "shade tree" novice really. I will buy a new pump and then write back to this forum with the results in a week or so.

First check that you have voltage at the fuel pump connector.If you have voltage then more than likely a pump. If you don't have power,check the 15 amp efi fuse on the fuse block and the contacts for corrosion.Fuse blocks don't have a good rep to begin with mainly because where they are located.

Does sound like you need a pump but you may have other problems also. This is from the manual.With the key on,fuses showing ok,should be a minimum of 7 volts(14max) between pins A and B on the pump harness connector. If you don't have voltage, shows to check wiring,load test the battery to eliminate it,plus you can swap the two relays around as they are the same. One relay is for power and the other for efi system. Next test would be to check pins on ecu connector or with a "known" good ecu.

04 no current to fuel pump
Thank You for your reply; I appreciate the information. In reference to the 7v minimum the manual says to check the A and C terminals and calls to replace the pump if was no continuity, then test battery, ign switch, harness, Load Shed-Relay and ECU. So the present stage I am at is the theory that an open loop or circuit would shut off the voltage flow to the pump wire 69. I am not familiar with the relays or where they are located?

04 no current to fuel pump "SOLVED"
Found a new pump,installed, and all systems GO! also, found wire shorts at the first connector caused by gummed connectors, used a tooth brush with dish soap to clean the female side then injected new dialectic grease into each one, worked like a charm.
