GSXR fuel injector not working went through fuel pump thoroughly and injectors as well next step to diagnose electrical to the injectors individually off the bike each one works
Fuel pressure regulator regulator pressure is supposed to open at 45 to 50 psi so it does not hurt the seals in the injector you can blow through mine which shouldn't happen so it was not allowing pressure to injectors
I went to a bike Pull and Save and got a used fuel pump for $180 she still kicking months later a brand new housing will cost you 300 to $500 that's why I bought it used
Here soon I will post a new video of me making a mod of external fuel filter and external fuel pressure regulator that is adjustable for pressure also tried removing pressure regulator running without it not a good idea blue my injector seals not a big deal just replace the injector seals could also be your fuel pump you can buy a new cylinder for $30 on eBay
@@jarrettehill1258 Okay my brot, I'll check the pressure regulator well because sometimes when the pump sends fuel, inside the tank I can see that the fuel pressure regulator drops the fuel
