Not quite sure what you’re doing but the fuel pump (via System Relay) only primes for 2 to 3 seconds when the ignition is first turned on. It doesn’t run continuously unless the starter is used (Start Relay is activated) or the engine is running. If the engine stalls the fuel pump is turned off after 2 or 3 seconds. If you turn the ignition on and then off you have to wait 10 seconds after you turn the ignition off before turning it back on again to get the fuel pump to reprime.
That’s what it’s supposed to do. What makes you think there’s anything wrong?
OK. I thought you were expecting it to run past the 3 seconds.
He said he has voltage on the Y/GN wire so the System Relay is working.
I can say, yes, at least 100k (and then some). You'll get much less life out of the pump if you run dry (even once) and most submerged pump systems rely on the surrounding fluid to keep them cool, so if you don't keep much fuel in the tank than will shorten the pump life.
as a mechanic("tech") i hate having things fix themselves.. too many times to count a bike comes in with a problem and i start checking things and pulling apart plugs to check power and grounds and continuity and such and it will fix itself.. don`t know where the problem was and will it come back as soon as the customer leaves the parking lot.. any ways yours is fixed so that is cool
I'm not sure I agree with this. If the pump runs dry, the engine quits running within two or 3 seconds because you loose fuel pressure. As soon as the engine stops running, the ECM shuts off power to the pump. So, it's basically impossible to run the pump dry for any length of time. So, it can't get hot, which is what would damage it. I run my tank down until the engine dies almost every time I ride it. I've got 2 tanks, with two stock v-rod pumps, so when one runs out I switch over. I've been doing this with the same 2 pumps for about 6 years.
