Forget everything and go back to basics imho
Can only agree!
My father was totally obsessed with blaming the imobilizer on my s3c after it "died" when he was out driving. I tried to reason with him, but with no luck. ended up with no imobilizer and a car that still did not start. I still tried to tell him to look at the last thing that was done to the car, still no luck. After he chased a ghost for a week he ended up at the last thing he had worked on, the fuel pump, one wire had came looseteacher
So what did we learn here?
Blame the things we don't understand hardly solve the problem :P
"DYC" ( Dredded yellow connector) first thing to look for in a "S"
After that just start checking everything in a controlled order how boring it seams to be!
When thats done blame the imobilizer and remove it!

Thank you all so much for your help!!

Got the little minx started Yippy, so nice to hear that noise.

Not sure but think it had something to do with the wiring to two sensors at the front of engine (on inlet manifold near side), not sure what they are as can't find them in bible or haynes. Anyone know what they are? Just nice to get to know the old girl.

At least my wiring skills are up to removing the immobiliser which is a good think as that was playing up anyway.

Next thing to sort is when rev'd she is slow to come back down to tick over, could this be the tick over valve on front of pendulum ? And how do I clean or repair it??

Hey get me I'm learning fast.

And thank you all so much, really is a great help.

Larger temperature sensor for ECU?

smaller temperature sender for dash gauge?

Unlikely to be the problem but lots of other wires there you may have inadvertently "wiggled" ?

Mr Phillpot,

Well at least I know what they are now, it was the small one I think, now you have said it is unlikely to be this I am going to go through car on next nice day and have a good look around. At the same time see how she starts.

No yellow connecter block on ignition, wires are soldered direct to ignition switch, although this seems to have been recently done judging by the solder on carpet, I know it failed on headlights for MOT.

Will do earth strap for battery to bottom of swirl pot.

redcard Hey!!!
Maffe, you are a very naughty boy!

Don't listen to him! nono

As Penny will no doubt tell you, this is all you need:


Just make sure you get the correct replacement smoke. The S requires the negative earth replacement smoke.
The positive earth stuff is for earlier TVR models.

Good luck. wink
