hiya all was wondering if anyone could answer my questions?

which coloured plugs go to where on the back of the inlet manifold ?
the problem im having is the cold start valve, everytime i try to start it up cold with plug off it doesnt start, so i plug the plug on and it starts fine but then runs really lumpy untill i unplug the plug ? was wondering if any one could help me with my problem as im putting inlet back on as i speak,

thanks fot yout time

 

Sounds like you've got a coolant sensor problem mate.

 

ERST?

 

yeah erst does anyone know where theres a diagram or anything? or anyone had this problem b4 ?

 

Could be the Thermo time switch, which is in a water way in the head, underneath the cold start valve.

 

i think thats it cos ive had it out today and water came out of chamber that it was sat in, im stuckj its getting dark now and still aint figered plugs

 

any other help please??

any online manuels or anything like thaT ?

 

water will come out their when u take the plug out!

 

yeah it did so, so if running like i said at top post could that be the reason ?

 

right ive just put a stage 2 hybrid on my van tonite and im still having starting problems with these plugs ? does anyone have any idea what color goes where ? or anywhere i can test them ? any diagrams or drawings ? thanks

 

afaik, blue - cold start valve, brown, thermo time switch, green knock sensor, cant mind any other colours yellow i cant remember where that went. doh. im havin starting probs too, my car doesnt move much an come start time it jus turns over, needs someone to hold metering flap down, but once started runs a lil bit rough, then warms up its perfect. think eithe rmy cold start valve or thermo time switch is gubbed too !

 

think thats the problem im havin ! thankjs for the help !

 

My m8 had a probem like this only it was so bad on his that once it was started it would over fuel badly after 30secs and stall.

you need to make sure that the colours are as:

blue - cool start injector.
brown - thermo time switch.
black - aux. air valve.
green - knock sensor.
yellow - sensor under inlet (cant remember name but its also yellow )

if you have these connected different it might cause your problem.
if you think that your cold start injector is not grafting unscrew it out of the inlet and see if it sprays fuel out (but watch your eyes it can go everywhere )
and if it aint swap the brown inlet sensor for a different one xr3i also have them

 

thank you very much

p.s where abouts u from in north east ?

u ever seen my van about ?

 

I had cold starting problems a little while ago, we checked all the sensors, plugs, cold start etc and they were all fine !! We were stumped for days and it turned out to be the wires going to the EMPA on the side of the metering head, they had snapped due to corrosion inside the protective sleaving ! we connected them back up and the car started first turn of the key !..................something else to try if you havnt allready fixed it !

yellow is the coolant sensor

Also, take off the cold start injector and crank, this should spray for a maximum of about 9 seconds I believe, if it sprays continuously then its a problem with the coolant sensor.

Other things to look at include, aux air valve, maybee an air leak somewhere, you could also try a different fuel ecu.

Hope this helps, Duncan

 

if thats right mate then mine is fooked !! heres a pic of mine. the cold start is yellow on mine and where the yellow circle is, its a round temp sender like the one on the thermostat housing but im guessing it should be a 2 pin connector cos ive got a blue connector (which is sposed to be coolant temp sensor) with nothing to connect to!!
