I thought I post a problem that I have since I own a cosworth.
It wont start at the first try. When the engine is cold and you try to start, it will crank until the battery dies but it wont start at all. At the 2nd attempt it starts, but runnin on 2 or 3 cylinder and after a few second its runnin on all 4 or it dies again. And on the 3rd attempt it starts right at the button.
And that happens everytime the engine is cold.

The strange thing is, I had the same problem in my Escos!!

 

i have the same prob in my 2wd, i need to put some accelerator on a bit and keep it revved at 1.5k for around 30 secs before it idles by itself

 

So the only common thing is the teperature ?, I would change the CTS and see what happens.

CTS - something temp sensor?

 

Had changed those, on my saff and on my Escos i had and nothing helped... also changed the commom parts like phase and crank sensor

 

Did you solve the problem?
If yes - please tell me how to solve it because i have the same problem!

best regards!

 

No, not solved yet, still wont start the first time

 

I would rig up a light to the fuel pump to see if that is being triggered, either that or power it direct next time it is cold, so you can rule that out if it's the same.

Fuel pump is fine, had changed it in my Escos to an uprated one and also the presure gauge says everything is ok...

 

sounds like the whater temp sensor is sending the wrong info to the ecu ? or its a wiaring harnes falt

 

I would also bet on the wireing, cos sensor changed and stil the same. But if I measure the wires from ecu to sensor everthing seems ok...

Maybe I`ll change it again, cos hat the problems with my icv, was new and fooked.

 

Coolant Temperature Sensor or sometimes referred to as ect (Engine Coolant Temperature Sensor)

thought I dig out this old thread, cos I have finally solved the problem

After changed and tested every sensor and wire in the car I`ve found the problem now.

It was the chip....have it changed now for an MSD one and it starts at the first turn of the key!!!
I think the old one wasnt developed right, cos I uses a lot of fuel, around 12liter at 100km.
Thought it was right, but in the last few days i managed 9,5 at 100km

 

Had a similar problem with my car, was the water temp sensor
