99 1.9d F8Q Kangoo/Clio engine: injector question. - carlwest
hello,

i have a renault kangoo 1.9 diesel f8q engine , does anyone know how to check the no 3 injector its the only one with the electrics going to it this is what it says on the manual cd ive got

The needle lift sensor is integrated to the injector
holder (cylinder n° 3). Its function is to transmit
the movements of the injector needle to the
computer. This allows the start of injection to be
deduced. The computer processes this information
and uses it to compare the advance requested
to the advance corrector on the pump to the
advance actually applied . In this way, the system
works as a closed loop.

but it doesnt say how to check how it works

any ideas please

cheers

slt

Why do you need to?

They're typically around 100 Ohms and you check their signal with an oscilloscope.

Before you chuck any more bits at it; do a compression test.

update on kangoo,

havnt got round to the commpession test yet as i need to put it back together

the latest ive done is to check the timing belt, i have set the engine to tdc using the mark on the flywheel then using the timing tool that holds the crank (a screw in pin) and tried to put the belt on using the marks on the new belt but the marks dont line up its 2 teeth out , i wonder if the belt is the write one? maybe too many teeth ? i have checked the belt on there website (dayco) and its showing its the write one.

any ideas please

IIRC it's got a flimsy notch on the back that locates into a keyway on the cam; they do shear and that could be your problem?

Is this one of the engines that needs the cam pulley replacing at every belt change?

I can't remember the years and oval plate numbers that need new cam pulleys; but there were major problems with the Renfault 1.9 diesels - so bad that many independents wouldn't touch a belt on them as they had been bitten too often through no fault of their own.

The dual-mass cam pulleys were supposed to stop their belt fretting problem - but caused mayhem with the, joke, locating notch.
