Hi all 

I have a yz250fx ,while riding on the weekend it just stopped and wouldn't start again , turns out the fuel pump wasn't coming on , i put a multi meter on the wires going to the pump , i have voltage in the negative wire .

Anyone had this issue or can shed some light on what it could be 

Cheers

The ecu probably switches the -ve terminal to power the pump. For what ever reason the pump isn't being switched on by the ecu. Maybe fuel pump relay?
