I'm just hoping someone has any ideas about what's wrong with it now. Rolled it out the garage and tried to start, nothing, all I get is the whirling sound on pressing the button. However, it doesn't stop after a couple of seconds like normal it just continues. I thought it could be fuel but I've just put 2 5l cans in. Any help will be greatly appreciated. It's a 4.2 1996.

If you can hear the starter solenoid being fired then it may be the 100A Fuse, if not then potentially the immobiliser key has been tweaked from its resting position.

When you say when you press the button, do you mean to start it or just to then the ignition on?

I have just replaced some of the carpet next to the immobiliser socket, I did have to get a little physical to remove the old stuff. It's the black button on the steering wheel, usually I press it there is 4 to 5seconds of whirling and then it stops, now it's continuous. Going to check fuses now, fingers crossed.

The whiring is the fuel pump priming.. What happens now when you press the black button for a second time?

I've just checked the fuses in the boot and none seem to have blown. Are there any more in other places, there is no 100a fuse there or are they the bigger block type fuses? Cheers for your time.

If I press the black button a 2nd time it tries to turn over but not enough power left in battery. I've tried jumping it but no luck.

It needs a fairly juicy jump.. I end up using my 320d running.

I'm wondering if I have pulled a wire or somthing when changing some of the carpet. I've had a flat battery on it before and it jumped no problem, I'm worried about why the fuel pump is constantly priming and not stopping like normal. Is it an auto electrician or a mechanic I need? Thanks everyone.

If you'd damaged something to do with the immobiliser the fuel pump wouldn't prime..

That's a relief because I haven't got a clue about electrics. Do you think it could have something to do with fuel? It had 1/4 of a tank when I went to move it last week and it wouldn't start, I assumed it was too low on fuel, found out 1/4 of a tank is actually an empty tank when I first got it. I put 10 litres in now though.

I managed to run mine out of fuel the other week.. Ended up having to replace the fuel filter, as it ran like a bag of crap after.

I think it's definitely worth a try. Did you do it yourself? If so could you point me in the right direction of where it is, cheers.

Fuel filter is in one of the rear arches. I forget which side. Have you tried charging your battery properly? I have struggled to jump mine in the past. Mine lives on trickle charge now.

Most starting problems and strange electrical gremlins I have had in the last 12 months on 4 different cars have been solved by attaching a fresh battery and trying again.
I would urge you to stop spending your time randomly changing things that probably don't need changing, and fit a new battery first.
Unless you tell me otherwise, your present one is probably old (they have a 5-6 year life, less if allowed to go flat regularly), and has been knackered by the long periods not using the car.

That will eliminate the most likely cause of your problems.

By the way, the last starting problem I had was last week - wife's Saab wouldn't turn over, having been fine the previous day. No, she hadn't left the lights on. laugh
Strange bongings, and warnings on the dash.
Tested the battery with my multimeter, 12.4 volts.
Puzzled, I had expected 2.4 volts, and the battery looked pretty new, but we have only recently bought the car.
Took the battery to my local Auto spares indie, they stuck the battery tester on it.....61 amps. It should have been 610 amps.
New battery purchased for £55, inserted in car by me, car now works fine.


PS
My TVR has been the one car I own that has been fine throughout, of course, no battery problems, but I use it every week.
The others were German and Swedish rubbish. Nuff said.

Thanks for the advice, it probably is quite an old battery and it does flatten in less than a week if I leave it locked with the alarm on. I'll try swapping the battery first. Cheers.

Yup, IMHO you had already hit the nail on the head, I just applied the 6 lb lump hammer.....
I/we could still be wrong, but at least this will eliminate the obvious.

I am just remembering the hours I spent trying to fix the non-starting problems on my Audi A8 a couple of months ago. It had had a new battery in November (Exide Excel), and it took me hours to realise "it MUST be the battery", check the voltage, take it back to the shop showing 10 volts, get it tested by them, and get a replacement FOC. It was simply a duff cell in the almost new battery, but even one cell down it won't start the car, and that's only a 3 litre V6.....
At one point I had six different fault warnings on the dash display

I've just fitted a new battery all is good again, I'd be lost if it wasn't for this forum. It took a bit of fettling but was pretty straight forward. Thanks for all the advice, I'll be back next weekend with a fresh problem.
