hello

a friend of mine owns a mk5 rs2000, its chipped by wouter bollen (dutch ford RS tuner) the emissionstuff from the exhaust manifold is removed properly, magnex from manifold till rearsilencer ,and a set of wilder cams in mounted.

the car drove properly till an certain day, that day the following happened:

it started realy bad and he had to keep his foot on the throttle or it would die, when the car is warm its all over en it runs extremely good.

normaly when you turn the key you hear the fuelpump a few seconds and then it stops when the system is on pressure.

when i turn the key now , the pump buzzes an stops then it buzzes realy unregularly, and dont stops, when we try to start the engine ,the fuel is comming out of the exhaust connection (manifold under car) it smells extremly of fuel and the car starts but you have to floor the pedall for 1500rpm realy bad and rough running.

we cheked al wires ,replaced the fuel relay , cheked hoses and stuff but still nothing found.

i was thinking of a sensor,or a injector that stays open.
i had more cars that run bad when cold and that was the coolant temp sensor for the eec, but this one is awfully bad and i think its not the coolant sensor.

im hoping for input from someone becauss we are desperate and a car like this should be driven and run properly, come on its a ford .

here in holland every one says thats it or thats it, but al those things they say should have influence on the car`s running cold and warm and this car only runs bad when ist cold.

no one has any idea?

Sounding like a fusebox problem to me something electrical

 

that fusebox seems to be a weak spot on these models inst it?

but at this car it looks really nice and tidy, and if it is the fusebox, its likely he runs warm bad to.

is there some way we can put it on a diagnoses system ?.

It is a week spot mate ive had mine changed cus it was doing all sorts of weird stuff when the engine was hot or cold i suppose you can take it into ford to get it connected up to the computer and see what thats saying but it will cost you mate

 

costs are not so important as a good running car.

we also hooked on an original unchipped eec, but did the same as the one that is remapped/chipped.

feul relais replaced, nothing
all the connectors ,nothing

its a bit of a pain in the , well you know.

now a pump question: does the feulpump have a sensor for pressure or is there a kind of sensor that says hey buddy i have enaough so stop it.?

when you you turn the key it pumps a few secs and stops but this one stays pumping unregularly, maybey he pumps the engine full of feul , caused by an injector that stays open, but even then it must run warm bad to?
