Youve tried nearly everything, What have you tried, Fuse,Relay? there is also a connection under the rear seat that has a habit of burning out?

Is the new pump needed because the old one had a problem?

yeah i tried the fuse and its fine but as for the relay only relays i could find were on the battery side under the bonnet and they are in japanese and i found the connection under the seat and that is also fine maybe there is some sort of cut of device

Britishdaddy

no mate i had to upgrade from a standard fuel pump to a 255lph fuel pump as i had upgraded other parts of the car

Britishdaddy

what is the small tube thingy that has a pipe from the air filter to it a pipe from the wastegate to it and then goes to the inlet if thats what is called

Britishdaddy

The fuel pump will only start (Prime actually) when the key is turned to illuminate the dash lights, It does not run continuosly unless the engine is running.

If fuel pressure is already at the correct level when you turn on the ignition you will not here the pump prime the system.
Do you have an immobilser ?? Turn the ignition on then mobilise your system, Does it prime then ??

no i dont have a immobiliser and thats what i meant about when dash is lit up (acc) and i still cant hear the pump fire up but doesn't start at all and cant smell fuel

If you refit your old pump does it work ?? You may have a faulty new one !!
But a 12volt spike type electrical tester & test the live feed further back from the fuel pump plug. To see if you have a break in the wire at the connector end
Like i said if fuel pressure is sufficient when the ignition is turned on, you will not hear the pump run/prime momentarily..

Tester like this

The relay is under the dash driver side up high. There is a bank of three there. Cant remember which is the pump though.
