having a few probs my my cossie at the mo

it keeps overfueling, done it 3 times now in about 3 weeks

was just sat there in it last nite with the engine ticking over then it died and wouldn't start again, you have to leave it about 30min til it starts again

had a new fuel pump fitted n the wiring re done about a month ago, and a full set up if that could be anything to do with it?

any ideas

 

is it a 4wd??

 

yep

 

3 multi loom plugs over the back of the engine bay ...
i can bet if they have not been sorted out its due to one of them .. they are a real pain in the arse .... either that or map sensor
mine will be done ready for next year ...

easiest way is to pull the connections apart and use a good switch lubricant on them .. not wd40 tho .. just push em in and out a few times ...

 

ahh bugger! know what you mean but dont have them anymore

they've been chopped out and rewired

just had all that lot sorted @ tuners as it was a bit of a mess

 

so .. possible map sensor .. im guessing now .. only cos mine was diagnosed with the exact same problem .. sat there all happy like .. then just turned itself off .. wouldnt restart and stank of fuel ...

 

ditto

know if it can cause damage to the engine? if i still run the car?

Water temp sensor ? I seem to remember my saff 4x4 doing similiar but it was a few years since now.

 

[quote=charlie luciano] fuck, best get back on the phone to NMS

 

As has been mentioned, if the (blue) water temp sensor that feeds the ECU fails, it thinks it is -52°C and runs permanent cold enrichment to compensate .

 

Mike will secs monitor help find the fault,as my 3dr has a similer fault

thanks for input lads

are there any checks or repairs i can do myself?

also as its an intermittant fault will any tests/fault diagnostics show up any faults when it seems to be running fine?

cos as i say its only done this 3 times now in about 3/4 weeks (n the car is my daily drive)

 

If it is one of the sensors that is monitored, then yes it would (such as TPS, water temp, MAP sensor, battery voltage) .

 

mike, can i pick ya brains

whats this water temp sensor look like & wheres it situated?

whats involved in replacing it?

 

Back of the head and it's a bitch to get to on 4x4s .

Looks like this:

fuck, so will be quite hard then with my big shovel hands

hows it fitted? can i just replace it and job done? or is some sort of set up need?

cheers mike

 

Id say map sensor

 

mine did exactly the same and was my map sensor

 

Just unscrews and is a direct replacement. HOWEVER, I have know it to be the wires that fracture where they go into the plug when disturbed and not actually the sensor itself....

 

nice one! thanks for the help mike, i'll check the wiring out as well

cheers rab/dicko

regarding the map sensor - can that just be replaced as well?

 

Yes it can .

 

topman cheers mike

 

sorry bttt need to ask another question

also when first starting it up in a morning it idles high (1500-2000rpm) and fluctuates, is this anything to do with it?

and is there a way of testing the water temp sensor to see if its failed?

cheers lads

 

water temp sensor is a complete pig of a job .. whoever designed it there needs a good kicking i did mine from underneath... but its not fun..

 

i can see it now.... i'll start there for half hour staring at it then think fuck it i cant be arsed it looks like a blag



anyone? rainbum?

 

could be the idle speed control valve.

unplug it next time and see if it idles ok.

 

if you feel down between the head and the oil dipstick you will find it ..
make sure it dont wiggle and the cap is on properly
