Hi everyone
I am a new member and own a sierra sapphire cosworth rally car[my third one!]
It has stage 1 chip and grey injectors.
The car was running fine but suddenly would not tickover but still would pull on boost .
I have just discovered the sump is now filling up with fuel;any suggestions?

 

Sounds like it is running way too rich.
Measure map-sensor signal, coolant temperature, intake temperature.
Check hose to map-sensor and hose to fuel pressure regulator.

 

The injectors are far to big for the chip

 

I thought standard injectors were used with a stage 1 chip?

 

He states hes running greys

 

Thanks for your input and I appreciate the greys maybe unnecessary but the car ran smooth as silk with them before with no cutting out or misfire.

 

What he ^^ says, you should have the STANDARD light blue coloured injectors, the injectors are fine but NOT with the setup you have, do NOT run it at all and change the oil before you next use it, if your lucky you may not have done any major damage!

There's no such thing as "unnecessary changes" when electronics are involved.
You need a consistent package, not a combination of good parts that don't necessarily form a set.

So, chip, map-sensor, injectors, fuel pressure and turbo restrictor, they all have to match.
What map-sensor are you using? (2, 2.5 or 3 bar)
What restrictor is being used? (None, 38mm, 36mm, 34mm, 33mm, 32mm)
Is the car build to FIA specifications and if so, which one? (Grp A, N)

 

Hi Matt,
Thanks for that;I just cant underdstand having done about 50 hard miles with no problems the sump is now filling up with petrol.
I f standard injectors would solve the problem I will be happy but why wasnt the problem there before.

It was!!! dont take long to get fuel in the sump with the ammount of borewash this combo would have given. May already be too late.

 

As Rod says!!

 

its over fueling, needs a set of yellows or greens injectors, and prob needs a chip to, if it hasn't borewash and done the rings....give joe@gsmotosport a ring 07940 181847 as im sure he will have injectors and he can map it for you glw it mate

 

Firstly those injectors on a stage 1 chip are wrong, unless someone wrote the chip for greys but I cant imagine it. Do you know who's/what chip is in it?

How long have you owned the car/how long has it been runing ok prior to this problem?

If you are intending on starting the vehicle again to investigate further then do an oild change before you do so.

 

Thanks for your input everyone,I will let you know how I get on

 

Thanks everyone;I have fitted 4 brand new greys and it is running like a swiss watch.

 

lol still using the wrong injecters for stage 1 you should have fitted standard ones then taken it to be set up/looked over

 

whats the bet in another 50 or so miles your sump will be full of fuel again

everyone on this thread has stated you are running the wrong injectors as they are too big - i would also bet the chip is not suited to your engine too.

I would put standard injectors and get it set up properly by a reputable tuner - otherwise you will forever be having problems with it

 

Id like to see the idle C0% with that setup. If its under double figures Id be suprised
Dont you just love it when people ask for advice, then ignore everyone

 

The OP knows best

 

Nothing like a bit of petrol to lubricate your bearings.

It may of course, not be a stage 1 setup at all. Could be a stage 3 / 3+ and just had a leaky/faulty injector. Although you would have seen this when looking at the plugs?? I doubt all 4 injectors would have been faulty.
