Great video. My K1100 has been laid up over winter. I've tried starting it but the fuel pump is not priming (whirring noise). Any suggestions? The fuse and electrics to the pump are fine
Thank you, I'm glad you enjoyed the video! Assuming the ignition switches and wiring to the fuel pump are ok, I typically check the fuel pump relay input and output voltages (at the relay) during key on. If either is missing, the pump won't function. If both are present, it may be time for a new pump.
@@soopa2doopa268 Thanks....I've now stripped everything out of the tank because I could see perished plastic on the electrical wiring. I've tested the pump direct to a battery and still no noise, so I assume the pump is at fault like you suggest?
To be sure, with the fuel pump disconnected, I also measure the DC voltage at the ring terminals of the fuel pump with the wires pulled well outside the tank, with the test leads insulated from each other, metal and any fuel or fuel vapor. This is how I know if power is actually getting to the pump. I keep the ignition powered off until everything is safe and correct, ready to measure the voltage.
Hey guys I’m buying one of these and the guy said the wires broke off from the pump. Would it be worth buying the bike for $500 and just replacing the pump???
Until the broken fuel pump wires are safely isolated from the tank fuel and vapors, DO NOT energize the fuel pump circuit. If this is the only defect on the bike, it's likely worth $500 or more. If the wires broke off the pump, the pump, itself, may still be functional. Why and/or how did the wires break or become disconnected? I would thoroughly inspect the bike before purchasing, including testing the fuel pump wires for voltage, with the wires external to the fuel tank, far away from any fuel and fuel vapors. (explosion hazard) If you're not experienced or properly safe with electrical/electronics and fuel systems, let a professional mechanic handle it. I would pursue this bike, as it may turn out to be a really good deal.
