I had hydraulic lock on a Renault many years ago - drove through some deep water, not realising that the air intake elephant trunk not only went down to bumper height and then back up again, but 160,000 miles of motoring on mainly country roads had pebble-dashed said trunk, so that there was a huge hole 6 inches above the road. Car sucked in water, tried to compress it, cracked two cylinder liners. Result, plenty of suck bang and blow, no squeeze = new car required.

I guess you can do the same thing with unburnt fuel - flood the engine with liquid and then try to compress it. From your description you turned the engine off in time to save it, but no way are you going to attempt to drive it to TVR Power.

No way, it's all booked in to be collected on Thursday morning and delivered to Power, so I will keep all you guys updated with progress as I hear anything, cheers.

Keep us informed Matt - I know it locked up when we were playing but that was only on ignition not on a run so I am sure no serious issues should have resulted.

Wish I had brought my multimeter we could have checked more of the ECU end out, either way TVR Power is the place to fix it. Have a good holiday and it will be all fixed for when you get back.

Right guys, time for an update for all those that are interested. I spoke to Jason at powers on Friday and he had it all running sweet. It was indeed exactly wheat he thought it was originally, which was a section of wire that had rubbed through down the back of the engine between that and the bulkhead. They have replaced this section along with another bit he said looked a bit suspect and could probs in the future and for a very reasonable price I have to add.
He said that this had indeed caused all the injectors to stay open every time the ignition was on.
Now they are completing the 12k service and also removing both manifolds, cutting open, removing pre cats and welding back together then fitted back up with new gaskets obviously.
Should all be ready for wed / thurs and I can't wait to have it all spot on and sounding even better. driving

Matt, if you've got it back on Wednesday you ought to bring it across to Earls Barton for the evening meet.

If I have it back Richard I will do without doubt, if not then I may nip over in the golf still. You got your high revs issue sorted out yet?

Changed fuel pump yesterday for a higher flow rate model, seemed better this morning but it was a bit wet on the road on my journey this morning (6.30 to 7.30 going east) so didn't really floor it. Started back home this evening and after pulling like a train halfway home have developed a misfire all through the rev range so it seems as though the problem has expanded, hopefully easier to identify now, I'll have a better look in the morning when everything's cooled down properly. See you on Wednesday !

That could be something as daft as a plug lead popped off. Good luck finding it.

Thanks for meeting up this evening. Iain (bald bloke who asked all the questions) was very impressed with you knowledge and the quality of your install.

I will be getting the cleaning kit out tomorrow - I simply hadn't noticed how dirty my car was until Chris pointed it out......

No problem meeting up Anthony, it was nice to see you again. I'm not sure about "knowledge" it's just what I've picked up along the way. I certainly hope the misfire is something simple but I think it's affecting more than 1 cylinder, things under the bonnet were just too hot to have a proper poke about. Hope you got home ok, see you again sometime.

Nice drive home thanks. Its perhaps what I like most about my car, it is staggeringly consistent.
If you cannot find the fault tomorrow perhaps ask Mat to help you with it on Wednesday?
