Managed to stall my Chim in the driveway... I'm pretty sure it's flooded as it refused to restart.
I've tried cranking it over a few times with the fuel pump relays removed (it actually fired for a few seconds!), now I'm just leaving it for a few minutes more.
Anyway, while I'm waiting I've been looking around the internet for further advise and I've seen a few page mention a 'clean through' mode for EFI engines. Basically you floor the accelerator while cranking over and the ECU detects that this is unusual and cuts the fuel.
Does anyone know if the Chim ECU has this feature?
Time for another try...

It might do. My A6 floods in the same way if you just move it off the driveway and don't leave it running for a few minutes - this method gets it started. Much unburned fuel through the cats though I think - I'd remove the relays like you have, much less chance of costs further down the line. You can plug them in straight away and the car should start now.
I don't think it has, although I believe it would be possible to provide this if the ECU was remapped.
To start with just do a sanity check, confirm that you can actually hear the pump and smell petrol out the tail pipes to rule out the chance that it is some other problem and not just flooded.
The next thing to do is leave it for ten minutes for the fuel to evaporate and the battery to catch its breath. Then try again with no throttle.
If that doesn't work disconnect or disable the fuel injection system and crank it over with the throttle wide open for ten or fifteen seconds. There are several ways to disable it, ranging from pulling the wire off the pump, tripping the inertia cut-out, pulling the fuel pump relay or fuse, or disconnecting the triger wire from the distributor to the ECU. Use which ever you find most convenient. Leave it for a couple of minutes for the battery to recover again, and try again with no throttle.
Depending what condition the plugs and general HT system are in it's possible that it simply will not start no matter what you do. Once the plugs hae been really fouled sometimes the only thing you can do is throw them away and fit new ones. Old school engineers will say you can clean plugs up as long as they are not damaged, but in my experience it is very hard to do this effectively and for the cost of a set of new plugs it is not worth wasting the time.

Ditto. Started first time; as always, but tickover a bit lumpy, as it was cold. stalled backing out of my parking spot, straddling the car park exit lane. Sooooo embarrasing 
, my mates pushing me back into my parking place.....to the usual "get a proper car...typical tvr..." etc. It's just a case of sitting patiently for a few minutes, giving it a try and then some revs when it does catch.

started cold was just going to let tickover a little till warm then drive
but it ran for about 15 secs at 1100 rpm then just died
woudl not start by turning key
realised had flooded it
so walked away from it for 10 mins came back and fired stright back up
just reved at 1500 RPM for a min or so and was happy as larry after that
strange
will be going through all the steps next weekend for cleanign plugs,leads
and the step motor and will probley disconnect the ecu
but just been reading through so will do as many as the thing as people meantion
to make a little better
