give it a service...the fuel has probably gone stale which wont help the plugs to fire the engine up

Check for fuel past the injectors and spark. The stale fuel thing is possible, but I've used fuel way older than that sans problema.
If no spark andno fuel past the injector(s) it'll be the TDC (aka crank) sensor.
You might also try jumping it with the +ive to battery +ive, but the -ive to chassis earth or something solid and metal on the engine block.

I too am having a similar problem. The car was working fine up until a few days ago, as I drove it to and from the MOT station.
Put tax on it, got it round the corner from my house, all of a sudden the revs just dropped to nothing and I coasted to a halt.
Left it a bit, then tried to start it up again......nothing. Pushed it home and left it for a couple of days.
So far it has had (engine-wise) new plugs and leads (to cure a misfire) and a new crankshaft sensor (as it was showing similar symptoms to a car I'd worked on that needed this part). Still nothing.
All four plugs are sparking, and the injector is putting fuel through.
Tried jump starting as I've never had a problem starting it this way. Nothing.
It just turns over, but won't start, and I'm beginning to think I should push it off the end of one of the piers, as I'm at my wit's end with it!!

have you replaced the fuel filter?
so you must be missing spark, air or fuel as you say there is spark good, air maybe but might not be enough fuel

What reading are you getting from the two pole temp sender?

Diagnosed the problem earlier today. It seems the car is running extremely rich.
I understand that the mixture levels are controlled by the ecu. Is it as easy as simply getting another one from a scrap car (same cc obviously) and refitting in place of the old one?

i would say have a stab and the ECT (engine coolant temperature sensor) in the head would be causing this problem
its on the left side of the head as you look down it between 2 head bolts, think with a single spade connector on it

It did half start when we unplugged the injector, but then didn't run for more than about half a second cos no fuel was goin thru it.
Seems like when the injector is plugged in, too much petrol is goin thru. Would this sensor be causing this?
Yes, two pole temp sender.
Put a meter on it and either check that reading against the nominals yourself, or post it here.

I know it's been a while, I just got my car back after someone tried to weigh it in the other week without telling me!!!
I've just replaced the ECT sensor (1 pole) today. Whereabouts is the other sensor you were on about? Are they different?

You've replaced the sender for the gauge, I think.
Is this an SPi car?

That's an aweful lot. Check sensor, but also check that the earth side of the injector isn't earthing out causing it to fire continuously. Most likely cause is bad fitting where the wiring fits in the throttle body.
So its SPI, and you have changed the gauge sender not the ecu sender.
Your looking for the one on the back of the inlet fannymould, check the resistance.

What sort of figure should i be looking for? What sort of range should it be between?
Cheers
from 10000ohm @ 0C
to 200oh @ 90c
essentially, it should show higher resistance the lower the temperature and tere should be no spikes -- were you to do a graph, it should be a smooth curve.

Hi ,
I have a similar issue on a 2001 Brava which was previously running fine. I am hoping to pick some brains as I am new to this!
It would not start , although was turning over fine.
After reading some VERY useful posts on here I discovered that the fuel cutoff had been activated.
On resetting this the car would then start fine but only run for 10 secs or so & then revs dropped & it cut out again leading me to suspect the sensor or the switch was at fault.
Started in this same way 4 or 5 times no bother , but now won't start even after resetting cutoff & you can smell petrol which was not the case b4.
No warning lights & keycode light turns off ok.
Any ideas would be greatly appreciated- apologies in advance as I'm new at all this!
