R1 Relay's
Evening All
Just finished chopping odd bits out of the R1 harness and I'm not quite ready to start the engine yet, But I've noticed the following ...
When I power the wiring up the fuel pump runs for about 10 seconds then the relay clicks and it stops running, now if I press the starter button the
pump starts running again then stops as previously described, Is this normal for the R1 or have I chopped a wire out that I shouldn't have
many thanks
Tony
Sorry should have said it's an early carbed model 4xv i think, also no fuel tank or fuel pipes fitted

Most injection pumps will reach a set pressure and cut out.
When you have confirmed yours as working, any chance of a list of bits that you removed?
I have an 05 engine and I expect I will be stripping a lot out too!

when i put the key in and turn it on for power (not ignition), I hear a series of clicks from the fuel pump that get progressively slower as it build
up pressure (over a period of a few seconds)
once its done this, it wont do it again for a fair while.
oh, and I'm not sure its good to have the fuel pump trying to pump with nothing for it to do. if its giving up after 10 seconds you could be
breaking it. (i think my first one went in this fashion!)

hi tony its because you have no tank lines or petrol going to it
you might damage your fuel pump if you do this often

A fair few ECU's will run the pump for a set amount of time when the ing is turned on. Also as said the ECU will also run the pump for a few
seconds after the starter is released and engine has not started.
I have a pump with no pressure cut out and it does this so I know it is the ECU cutting it out and not the pump. This might be differnt on a bike as
i'm talking cars.

A bike pump clicks whilst it fills the bowl
after it fills it it stops clicking
yours most likely keeps clicking because as I said theres no fuel in it
