fuel pump V8s

[aquaregia]

The old girl will not start, well she fires burbles and splutters and dies, no response when throttle depresed, the fuel pump is making a funny noise as you turn the ignition on not the normal sound as the line pressurises. The car has a meta imobiliser. The car was running fine. All I did was pop her up on the ramps and hammerite the chassis and wax oil. Then the fault appeared. I think its the fuel pump, I was driving the other day and lost power, then regained it. As I drove the car to my garage she was very lumpy in second thought it might stall. Any ideas or suggestion appreciated.

check to make sure you havnt disturbed the connections on the fuel pump

Stick 12v straight onto the pump and see if it sounds the same. If it does - duff pump. If not - wiring/relay problem.

I bet it is the pump relay. The internals fall to pieces and shake around giving intermittant faults. Buy a decent replacement from Range Rover. I fixed mine taking it apart and removing the offending piece of insulation which was causing the problem.

Is the relay in the relay board with the others, or buried somewhere else in the loom? I've an odd electrical issue, (well, several), and had to wire the pump direct to the battery via a fuse in the boot. Just starting to think about sorting it properly..

Oh, if you've a Range Rover replacement part no I'd be grateful..

You have probably already researched this but the Rover lumps are prone to over fuelling from cold start, if you do not allow the engine to warm up to the correct temperature and turn it off, you may have flooded it causing it not to start. I had this problem when I pulled my car out the garage to wash it. (I note you mentioned you put yours on the ramp so I assume full temp was not achived)

If this is the case you might want to try drying all the plugs with a blow torch and even leave the plugs out overnight so excess fuel can evaporate. Mine started on the 2nd attempt of drying plugs as I have never had it since now I know to avoid intermitant starts and stops.

May not solve your problem but worth trying before spekding money and time??

Thanks, already knew that and eliminated the possibility. I've definately got an electrical problem somewhere backwards from the pump itself..
