I own a large turbo escort cosworth with a problem.The problem is that when I start the engine cold it starts ok. Let it idle to the normal temperature about 15minutes and it just cuts out. If I try to start again,it wont start. Engine cranks properly when starting. Let it "cool" about 5 to 10 minutes and it starts just like nothing ever happened. The prolem also appears when hot,after driving. I park the car,come back in about 10 minutes, try to start and wount start. When starting from cold no problems,always starts up properly. CPS sensor has been change today, but to no avail. Also tried a Coil, but again, car starts fine, then cuts out once warmed up.

I have noticed that when I turn the car to ignition, the sensor that is located to the right of the engine and is light grey in colour (located by where the boost hose goes into the engine, next to throttle cable) this clicks quite loudly and quick..

Any ideas as to what the problem could be as its eally starting to annoy me!

Thanks

spiky..

we are not too clued up on the sensors, but the one making a dodgy clicking sound was located on the end of the boost hoose (right hand side of engine) Light grey in colour

should have taken a pic but was getting dark and cold

Dilly

clicking sound is probably coming from the iscv, it's supposed to do that when you switch the ignition on

Your talking about the idle speed control valve Westy!

SPADGE

Still sounds like a problem with the temp sensor to me btw

Westy

iTrader: (1)

to be honest, i havent got a clue what im talking about spadge


Dilly - cheers, but not what we wanted to hear was hoping it was this sensor that was the cause

Spiky - it looks abit different to yours See the yelow plug on yours, just above the throttle cable, that was the one making strange sounds

Just lovely when we picked it up, but saying that, we were on the M1 pretty much straight away, so kept cool.. went in slow lane for abit, then it must have got warmer and died left it for 5-10 mins and started... then later died..

oh and thanks Spadge for that advise earlier mate. Was appreciated, considering you sounded well bunged up

But I forgot where you said the temp sensor was..

SPADGE

No problem mate!
The temp sensor is on the inlet side of the head right at the back directly below a coolant pipe coupling and is blue in colour

SPADGE

Temp sensor as shown mate

cheers spadge... so tomorrow morning will be checking that.. Is there a way to check the actual sensor to see if its faulty? Or is it a case of putting a different one on?

IE driving round yours tomorrow and buying one

Would this sensor make the car cut out after a certain point in that it reaches a certain temp?

Thank

SPADGE

That sensor is the only one on the engine that is affected by temps Westy (strangely enough )

Westy

might have a cold, but still got your sense of humour

Now that you mention it tho, does make sense Hope it is..

Would this Sensor currently be in stock at Spadges Emporium ??

SPADGE

The one pictured was replaced 5 days before i pulled the engine out mate and that is as near new as you will get from me
If you come for it on Easter Sunday just make sure you bring me a big fook off easter egg or or you will get is a slap

Westy

Seriously tho mate, will have a look tomorrow... not much to look at tho, and if its alright, we'll pop over to get it and try it out... Mar's, Snickers, what preference ?

SPADGE

Got to be Cadburys dairy milk but no homo caramel fillings please
Check the plug on the sensor isn't iffy as they often are!

Westy

iTrader: (1)

It is very hard to diagnose problems like this without seeing the car.
I/we can only offer best guesses.

Sorry, cant suggest much more DIY things to check.

Westy

iTrader: (1)

appreciate the advice so far mate

just gutting to see someone buy there pride and joy, and it goes wrong

maybe left best for A1 to check it out

While the engine is running, grab hold of the ecu and shake it !
Dont tug on the wiring loom too hard.

If the engine cuts then it could be a faulty ecu/dry joint, a fault connector pin or
a broken wire in the wiring loom.

Needle in the haystack I am afraid....

paddy heffernan

did you ever solve this problem i have same problem

Westy

New wiring loom in the end sorted it I think.. Was years ago I'm up gatwick at the mo but will ask the lad tomorrow when I see him
