Whats the year and cc of the car ??.. If the main power you mean the feed
(disconnected) is there AND you have a good earth then the pump must be u/s.
Believe it or not you can have 12v and a open circuit! either via a bad earth
OR no current flow(resistence).The best way to check fuel pump operation is
current flow /oscilloscope as current flow without voltage is impossible...

Thanks for the reply. she has ordered new pump from Camberley autos at
cost of £141.00, but we still dont know if there is a relay .from fuse
to pump.

Most of the time (thats why i need cc and year mate) the relay is situated
underneath the engine e.c.u. its called a double relay as it controls fuel
pump/ignition/ amongest other things ...mark

I think it is a Nreg and its asmall engine 1,1 so its under the e.c.u
unit i have seen that on the left hand side

Thats it mate usually brown.But if you have a feed there at least it means
its switching!(even though it may not be switching 12 v in some cases).. all
the best mark

Just been told the person put a tester on to the feed from the fuse
box.the one that gos to the pump and they had 12volts with inj turned
on.then it droped off still with inj on.so to me it sounds li8ke the
relay?

Going off what you say the relay sounds ok as its working then switching off
(to prime system).But its not the best location to test at the fusebox for
all the tester knows you may well have a open circuit from the fuse box to
the pump! (chances are you probably won't) you must always test at the pump.
After all it takes 2 secs to flip the seat up to get to it... mark

She had the pump tested out of the tank.by useing the batt supply and
the pump did not do what it is surpose to do.
