Thermo time switch V8

[braveheart 3]

Gents,
Can anyone confirm whether this is actually needed and could be just unplugged ?
I have been having a nightmare trying to find one EAC 1385 and they are at least £100 !
I vagualy remember someone saying it isnt necessary ?
Finally if i do need it where reliably can I get one ?
Many thanks as usual !

I had to replace a similar switch in my fuel rail. It's only the Hotwire that has it. The flapper system didn't have it.
It basically tells the Ecu to fuel more if the fuel rail gets hot so the fuel doesn't vaporise before it ignites. So I was told. I had running issues only when warm. When you unplugged the thermo switch from the fuel rail when hot it should have made a difference but mine didn't. I put a new one in and hey presto it worked.
It's a Range Rover item. You'll get it from Rimmers. That's where I got mine and it's not gold plated.

Hopefully we r talking about the same switch on the v8.

It just helps you start/idle when very cold. It has no effect after you have revved it a bit, even less in the summer, you can just leave it unplugged (if it's shorted) or plugged in (if it never closes). Or you can disconnect the cold start injector.

Are we getting confused here between the thermotime switch and the 9th injector?

Or do they both have similar symptoms?

Last time i asked Rimmers when i changed the coolant temp sensor (next to the thermotime) they were £80 and hard to come by

As I recall the thermotime switch operates the 9th injector - so you can disconnect either.

Thanks everyone I will do without it !!

I have always just disconnected it on the flapper systems as it's just not needed. It pumps in about an extra pint of fuel and is just not needed.
