Hi Guys
My wonderful 450 Chim (2000 model) has let me down for the first time.
Got in yesterday, car started but 'lumpy' - engine stopped as I tried to drive out of the garage. Fuel pump seems OK - plenty of chatter as I turn on the ignition, I've checked that all the leads are attached and the tank is full. Any idea are most welcome however basic - I am not a technical.......trying anything has got to be better than having to stare at a 'dead car'. Cheers.
Alan,
Has the car been laid up, or was it fine one day & buggered the next?
Not sure where you are in the uk but the damp foggy weather can play hell with a cars ignition system. As you are not to technically minded I'd suggest you get hold of a tin of wd40. Spray a coat of this onto the ignition leads, distributor cap & coil. This will drive out the moisture & if thats not the problem it won't do any harm.

Could be flooded... have you tried keeping the accelerator flat to the floor whilst cranking... don't pump it though whatever you do.
That doesn't make any difference in practice. The ECU increase the flow accordingly. If it is flooded, remove the fuse for the fuel pump and turn it over. No fuel can be injected and this will clear the engine. However if the plugs are already wet then this won't help that much either. The plugs need to be removed, dried, cleaned and it might start again but in some cases the contaimination can prevent a plug from working and in worse cases, replacing the plug is necessary. Check for a spark before refitting is a very good idea. 
yep as SHPUB says,but sometimes if you leave the car a few hours,then with the fuel pump disconnected or fuse removed crank with open throttle till it fires then with an assistant quickly replace pump fuse or connect pump before it dies from lack of fuel,you have to work fast but its easier than pulling the plugs,then run up long enough to clear the cars throat,in future dont start then turn off without warming her up ,not in this weather anyways its how this fault occurs(cold engine overfueling),not just TVR related fault.

Well I'm sorry but it worked for me... when the same thing happened a few weeks back... cold morning started fine in the garage, went to back her out too soon and she stalled... wouldn't start, flooded!!
I've used the same trick for years on a multitude of cars with ECU's... why is the TVR any different?
Mind you, that's not to say it isn't an electrical fault or otherwise.

Red V8,you are correct but sometimes if the said car is really juiced up you end up just pumping in more fuel making things worse,oh here is one ive just remembered you are try to unflood the engine by trying to get more air in with out the fuel,pull off the servo vacuum hose crank with no throttle this creates a massive air leak once it fires reconnect,i have used this method on late various cars with plugs that are a nightmare to get at,normally caused by the owner starting and shutting off repeatadly moving from drive garage etc.
