Rover 214i Stalling - could it be the inertia switch??

Hi,
   I am looking at a Rover 2.4i (L-Reg) with an intermittent stalling
problem which appears to be fuel starvation. According to the wiring diagram
in the Haynes workshop manual, there in an "inertia switch" in line between
the fuel pump relay and the electric fuel pump.

 So that I can eliminate this as a source of the problem, I need to find
this switch and bypass it.

 Does anyone know where on the car this "inertia switch" is located ???

Thanks in advance

I think it is in the boot on the right hand side in front of the rear light
cluster.  ICBW though.  Change the fuel pump relay.  My 214 did this one
night as I left work.  It would idle and drive for about four hundred yards
and then just die.  A change of relay and it hasn't happened again in six
months.  Does the fuel pump prime when the ignition is switched on?

This morning it happened to me twice. Each time the engine just died. When I
tried to re-start it, it just turned over without firing. I left it switched
off for 30 seconds and then  I switched the ignition back on and cranked it
but it still would not start. I then waited another 30 seconds and when i
turned the ignition on I could hear a humming sound from the rear of the car
(presumably the fuel pump) which was not heard the first time. This time
when
I cranked it, it started immediately.

This pattern was exactly the same each time - presumably the hum was the
pump priming/pressurising the fuel system.

I tried to look for the inertia switch but was not in the mood to remove any
trim so I have swapped the fuel pump relay with another oridentical to see
it if it makes any difference.

Thanks for the advice...

Could be the timing. Best thing to do would be to set your computer clock
correctly.

fuel pump relay you talk about is in the fusebox under bonnet .
it runs for about 2 seconds to prime fuel rail.
it does not run again until it detects engine speed

thats industrial standard. does not matter if its multipoint or single
injector.

It is in the centre console according to autodata and my memory.

My first thing to replace (at little cost) is the rotor arm (assuming your
year still has one)  as I had this fault on an earlier one, you could drive
for a while and then it would die, after a little coaxing it would go again
or you might have to wait.  AA diagnosed coil, I replaced that but the
symptoms were the same, so I changed the rotor arm just in case (although it
looked perfect) and the car went and kept going.!

Another thing on those that causes a lot of aggro is the vacuum pipe that
goes to the ECU, it can crack, or the nipple on the ecu can crack or snap
off, the resulting air leak makes them run terribly.

There is nothing wrong with your memory, it's tucked just behind the centre
console and can be seen if you lean in over the drivers seat with your head
in the foot well.

Agreed with the rest of the diagnosis, although I have known the pump and
pump relay to fail.  Also you get bad running with cutting out if the
crankcase sensor is going senile.
