Hey Everyone,

Its been over a year since I fired up the X1, and I am definitely having a few problems at the moment. The last time I rode the bike, the fuel line from the tank (just before the fuel filter) cracked and spewed fuel all over me causing the bike to cut out. I assumed the bike died as a result of lack of fuel from the obvious pressure drop. I was a bit frustrated with the bike at the time being that every time I have ridden it lately there was some sort of major problem leaving me stranded.

Fast forward over a year and I finally got around to replacing the fuel hose and filter. The problem now however is that the fuel pump will not prime when the ignition is turned on. I can hear an ever so slight hum for just a second as the ignition is turned, but it is not the very audible pressurizing sound and it is only for a brief moment.

Anyone have any idea what could be my problem at this point? I checked the fuses and they are all good. Swapped relays around, and the don't appear to be the problem. Could the ECU have known there was a pressure drop or fuel cut and keep the fuel pump form kicking on? Would pulling the battery and letting the ecu reset potentially help?

Thanks in advance.

If you have the ecm-spy and the cable you could test it, and see if there is any other problem

How much fuel was in the tank?

I let my S3 sit a spell (SC Summer) with hardly any fuel in it. I got the same symptoms in that I could hear it trying but it was definitely constipated. I found my fuel pump gummed up from ethanol sludge. I ended up replacing with a new (expensive) assembly. I see the same gummy residue in carbs from bikes that have sat a year or more.

Perhaps the same root issue? Just the pumps are available on eBay plus lots of used stuff out there.

I'll have to check if it is gummed up or not, I could definitely see that as possible. I would think however I could hear the pump struggling if that was the case.

Pulled the wires connecting to the fuel pump. I get power whe the key is on and ignition switched to on. It would appear as if it is pump related at this point. Hopefully i can simply clean it out and that will be that...Does anyone even sell a new pump for these bikes anymore?

Lance at St Paul https://sphdonline.com/ will likely have the NEW whole enchilada ... ~$300. Someone was selling replacement pumps for about $30 on eBay and various used ones kicking around

Not to take anything away from Lance or SPHD but highflowfuel.com shows a pump and regulator for $80.00. I think someone here had recently used them also.
