Engine will start but won;t rev and has very low power.
Switch ign on (engine off )pump runs for 10 seconds then stops. Is this normal?
when I depress schrader valve on fuel rail there's no "spurt" of fuel but when pump is running there's adequate fuel there.
Is there a pressure regulator?

The fuel pump should run initially as you describe ,It,s called initial prime and is normal.If you are able to carry out a fuel pressure check,that will tell you if you have good pressure that ,s what that shredder valve is for,mounting a gauge to read it,Are there any fault codes logged to help you.
