Sinnis Terrain 125 21 Plate

[MyNameJack]

Hello, I tried starting my bike today, and it fired up as usual. However, by the time I got out of the garden and to the entrance of the road, it cut out randomly. I thought, “Oops, I must not have had high enough revs,” but when I tried to restart the bike, it just kept cranking over and over. There’s plenty of battery power, but it won’t run. I turned the ignition off and back on to try again, but still nothing—it’s cranking over but won’t fire up. What I noticed the second time when turning the ignition off and back on again is that I can’t hear the fuel pump priming. My immediate thoughts are that either a fuse or relay has blown randomly, or the fuel pump has died. Do any of you have any suggestions on what I can try? There’s a spanner logo on my HUD, but I think it’s due for a service regardless. I can check with an OBD scanner to see if I get any error codes tomorrow.

Yes, there's a half tank of fuel yes there's Oil yes the battery is good. (sorry thought I would answer the more basic questions)

took the side ferrings off just now and double-checked all the connectors to make sure nothing was loose and the same issue persists. the startup is ok no noise from pump and starter keeps turning

Hi,

I'm guessing if you heard the pump prior to this problem then it's something to do with the pump. Fuse etc? Feed to the pump or the pump itself? Sounds like it may be a place to start.

The noise you hear from the pump, is the pump priming, so, it's quite likely to be fuel starvation.

Again that night when I turned the bike on and started I was talking with someone so I didn't notice the pump priming and now after the bike has cut out on me I can't get it to prime so I'm thinking dead pump

usually, the noise from the pump is noticeable and not quite its usually always something I wait to listen to then start the bike up but as mentioned above I was talking with someone at the time
