I Ride:
Bike won’t start

Hey folks- I could use some help. My FE 570 was behaving oddly during last few rides: stalling out while under throttle, most of the time a quick press on the start button got it running again, sometime I had to wait awhile. Then it stalled out completely during my last ride; bike would not start hot or cold- tried bump starting too. No go.

After reading up on fuel pump issues, I pulled and tested the pump with hot water and it pumped fine. I replaced it anyway with a CA Cycleworks pump and a new in tank filter. Bike still wouldn’t start. Ohm tested the spark plug which was a little low, and replaced, no luck. Checked for spark and it’s there. I pulled the fuel injector and cleaned it and tested for proper spray. That all checked out. Still won’t start and not sure what else to check. I poured some fuel down the throttle body and it did start after all the other tests.
I’ve also checked all the fuses.

Thoughts?

Thanks!

Check your fuel pressure should about 45 to 50 psi (just a guess) if so replace fuel pressure regulator
