Fuel pump problems
Discussion
On my way home from a blast across the countryside I could here the fuel pump running as if there was no petrol in the tank. The gauge read a quarter tank (it lied). The pump quietened down again until I was coming down my street. I just pulled into my drive and the engine died on me.
When I turn the ignition on there is no noise from the pump, usually I can here it priming.
The fuse is OK
I've put a gallon of petrol in the tank so I know there is some petrol in the car.
If you leave it for a couple of hours some petrol gets through to the engine as it will run for about 20 seconds and then die.
Two questions come to mind
1. Is the fuel pump knackered. If so is it behind the nearside wheel. Is it easy to change? Is it "off the shelf"?
2. Does the system need to be primed after it has run out of petrol. (clutching at straws)
The only saving grace is that I made it home. I would have had the p*ss taken out of me mecilessly had it happened out on the road.
Hope someone can help

Not yet. When I was speaking to the mechanic who looks after our vehicles at work he suggested I take a lead from the battery and put it straight on to the fuel pump to check the wiring. Unfortunately I am not quite sure where the pump is. I havn't been underneath yet to trace the fuel pipes.
Ken,
Agree with your mechy at work. I would put a test lamp on both wires at the pump first to see that you're getting juice back there.
On the V8 the pump is behind the nearside rear wheel. Once you jack up that corner, its obvious.
Does sound like a knackered pump though! I bet tvrcarparts can get you one PDQ. If not TVR at Barnet was where I got mine - -when my pump failed in almost the same set of circumstances. Get a new filter while you're at it.

It's not uncommon for the S pump to fail.
There's a filter inside the tank that can become restricted and not allow enough fuel to the pump letting it run dry and this leads to pump failure.
The pump is roughly central and in front of the tank on the S2.
If you do need a new pump, I suggest a replacement Bosch (Lucas is the standard fit) but the Bosch is a direct replacement and better quality. I did mine a while ago and posted the details on here www.parkersteve.dsl.pipex.com/sparts.asp

Took the rear nearside wheel off this afternoon to see if I could solve the problem. The pump is in a position that is almost impossible to work on unless you have a ramp.Anyway put the volt meter on the leads and there was 12 volts so it looked like the pump was bu**ered. I then put 12 volts directly on to the pump and I could here it click as the voltage was applied. It sounded like the pump was trying to turn. I kept tapping the leads on to the pump and eventually it started to turn. At first it started to turn very slowly and hesitantly. After a couple of minutes it was running well. Reconnected the leads from the car and stated it up. After a few goes it sprang into life. I have since taken it round the block and it seems fine. Left it for two hours and tried again still ok.
Think I may have cured it or at least kept it going to get me to the garage.
PS My volt meter has a decibel counter on it so i put it on the roof and started the engine up.
89 Db in tickover
100Db at 4000 revs
Didn't want to upset the neighbours by reving any higher.
