hello people can anyone tell me why my car is over fuelling.as it smells so rich and black smoke coming out of the exhaust.and you can smell fumes in the breather system.and the water looks yellow rust colour with like a oil film could it be the fuel pressure regulator seized open as the has not been run for 3 years as i have rebulit the car.


many thanks chris.

 

I would be tempted to replace at least the coolant temperature sensor, these do go out of range and usually mega mega rich, will be belching soot!!
I would also do a complete service with it having been sat, inc fuel filter and fresh fuel.

it has got new petrol tank fuel pump were do i find the coolant temperature sensor.

 

coolant sensor is the blue one at the back of the head next to the pipe that goes to the oil cooler!!

be concerned bout the yellow rust coloured water with an oily film thou.......

Has it got antifreeze in and when did u change the water last?!

 

no i have put antifreeze in it yet has i have put a new themostate.

 

The CTS (Blue) is back left hand side of cylinder head underneath plenum is hard to get at!

Coolant defo needs changing as well as oil.

also could it be the fuel pressure regulator thats seized open.

 

ok mate i will do that olso i removed a 17mm nut from the right hand side of block to put a breather system on and water type came out and when look in side the bucket it looked oil type put very runing.is this so.
