I believed I had plugged injectors from the bike sitting for a couple years so I pulled the throttle body and cleaned the injectors and fuel lines. Reassembled everything but now the pump doesn’t power up nor do I get anything on the dash. It’s like it’s not connected. I’m 99% sure I didn’t miss plugging in any connectors but anything is possible. I’ve pulled the tank on and off several times looking for anything I may have missed but not seeing anything.
Does this bike have a tip over kill switch that may have been tripped? Only thing I’ve considered but haven’t tried is disconnecting the battery and possibly resetting something that way but I have serious doubts that will do it.
Suggestions????

Thanks, Matt

I just remembered, initially I did leave one injector unplugged. I figured that was it but no difference after correcting.

Had a similar problem: make sure to plug a connector under the gas tank, plug it in all the way. There are two connectors: one in front for dash, one under the tank for fuel pump. Good luck!

I’ve plugged and unplugged the tank connector several times. I never unplugged the dash connectors but I’ll double check them this afternoon.

Follow the wires to make sure you didn't accidentally pull them loose somewhere else .
Also, might try taking them loose again and adding some diode electrical grease to make sure they make a good contact and keep them from corroding. Check pins for being bent or something on them. Only other thing I can think of is, somehow you blew a fuse.
Did you check that the kill switch is in run position, to activate the pump and it's in Nuetral? That may activate the pump.

I can head East or West, it doesn't matter as long as it's on 2 wheels.

I second that, check fuses and connectors. If those are in good shape, then you might have a wire problem.
If I'm not mistaken, both the fuel pump really and speedometer are on the same fuse (#3). Good luck!

Just mentally running down possible problems. Other than fuse and connections, there's nothing else I can think of the 2 problems have in common.

I had a few minutes this afternoon to look at the bike. I found the fuel pump fuse blown. Replaced it and everything seemed ready to go but still no start. I tried hooking a hose to the output of the fuel pump and turned the key. It sounded like it ran but only a second or two. Didn’t get any fuel from the line. I’m guessing it’s time to pull the pump.

Pulled the pump out. Tank inside was clear of rust which I was concerned about. I haven’t tested the pump but I did find the filter/sock was falling apart and there is a plastic hose that comes from the pump up to what looks to be some kind or valve or regulator that is missing about 6”! I’m guessing that may be some of the problem.
I checked local dealership. They only sell the complete assembly for the bargain price of $470. Amazon has pumps and related hardware for $70. Any other choices that others have had good experiences with?

Also noticed the coiled wire loom stuff was very crumbly with quite a bit already in the bottom of the tank. The pump kits don’t come with this stuff. Not sure if auto parts wire loom material would survive submerged any better than the original stuff.

I got the new pump installed this afternoon but still not running. Now I’m guessing the regulator must be plugged. I think I’m hearing the pump run a few seconds when turning on the key.
Could someone tell me how things should work on this system?
Is the pressure switch that shuts off the pump when max pressure is reached internal to the pump?
Can I buy a new regulator or can it be disassembled and cleaned?
With everything assembled/connected except the fuel line, should I get fuel pumping out of the pump assembly when I turn on the key?

Thanks again, Matt

Finally!!!
I was really scratching my head this afternoon but it is finally running. I replaced the fuel pump yesterday but still wasn’t getting fuel flow. Pulled the pump today. On the bench the pump ran fine. Put it back in the tank and it wouldn’t run. I took it in and out 3 times with same results. Only thing I could think of was wires/connector inside didn’t make good contact while submerged in gas. I changed the connector and wires to the new one supplied with the pump(should have done it before but I didn’t have any ring connectors) and it worked. So glad this mess is over so I can move on to the next mess!

What I thought was the pump running before wasn’t the pump. Not sure what is making all the noise when I turn the key but now I can hear the pump in addition to the previous noises.

Thanks again,
Matt
