Yamaha EFI no fuel flow
Recently installed new rings and gaskets in my YTF1 cart. After trying to start it no fuel flow. It has the throttle body. You can hear the fuel pump kick on but wont flow to carb. It has only 5 volts to the TPS. Is that normal? Removed the injector no flow at all. Can shoot fuel in and it will start briefly. Any ideas.??

Re: Yamaha EFI no fuel flow
Do you have a fuel pressure gauge? The pump pressure should be 248 +/- 14 kPa (2.48 +/- 14 kgf/cm2; or 36 +/- 2 PSI) fuel pump is one of the main issues I deal with on the EFI Models...
