No fuel pressure at startup

2013 CRF250 is getting no gas at startup. I have to manually connect a 12v battery to the fuel pump plug & run the pump a few seconds to prime/pressure the system. With that done it fires right up (1-2 kicks) & runs great until you shut it down or stall it. What's gone wrong here? Any suggestions?

One of your sensors has failed, telling the ECU to not energize the pump relay....or the relay is bad. Have you checked the fuses ? Capacitor harness? Tip over sensor ?

New to the EFI systems & haven't checked these items. Where are they located? Honda Manual is very vague. Would a better svc manual be better?

You need the FACTORY Service manual not the Owners manual.

You can download it for free from the Honda Powesports website.
