( Optional) Fault Codes: No fault codes

Hi

Recovered van as non-runner. Found to be out of fuel. Replenish fuel, bled system, started and ran.

Van was booked in for service anyway. Reversed onto ramp 2 hours after getting it started.

Carried out 108k service, new fuel filter(Purflux)
bled fuel, started and ran. Van was moved of ramp,
discussed with technician abour carrying out brake efficiency checks on brake tester to see what bearing rusty rear discs would have.

Techie reversed back, checked fronts, reversed it back further. Switched off, checked and topped up engine oil. Then it would not start.

Checked filter installation,by passed filter unit.It will start with a sniff, but stops without it.
Fuel rail pressure cranking is 298-305 bar. Noide
lights on injector multiplugs show pulse. No evidence of leak back with pipe disconnected off injector return, but does leak back from pump.

Had a guy in(Airbagman)with Renault clip.No codes,
Cranking speed 298 rpm. Would not show injector pulse(but think noide lights confirms this). But it show Glow Plugs deactivated. Got 12 volts @ plugs. Disconnect any component, faults are logged.

Anyone able to throw any light on some hidden
known fault/quirk with these please ?

Thanks

Phil

HI Phil,
Just thinking out loud and first impression, but perhaps it has a fuel inertia switch that has been tripped when getting out of brake rollers !

hi
i thought the 2.0 trafics had piezo injectors, if that's the case leakoff test needs a different bit of kit to the norm. if it was the pump you wouldn't show fuel rail pressure like the amount you've got but then it wouldn't if you've got leaking injectors i assume. back to work with clip, a wiring diagram & possibly a leakoff test, looms play up on these all the time as well

this is the type of gear i meant

Hi Keith,
The pump is on the end of the cylinder head. There is an aluminium body bolted to the back of the cast housing of the pump,held on by 4 or 5 torkx bolts, is 20-25mm wide,no pipe unions on the ally housing,only on cast body and is irregularly sided.Is this it? What i have found is they are common to the 1.9DCI but no reference to the 2.0DCI.

Regards
Phil

try the pump in the tank as they stick.

if you thump the tank in the middle it often starts again

Phil, If the clip is telling you the injectors are not being driven then they probably aren’t. A noid lamp really doesn’t tell you much. I think you need to check the inj while it has healthy pressure and if not right then ask yourself why. CKP/CMP would have to be next.

Is 298rpm a bit fast, compressions maybe? Remember it doesn’t take as much compression to fire a sniff as it does Diesel.

All pre 2010 2ltr M9R'S have pezio injectors

Firstly for Alan, The clip did not have the function to display Injector activity, leaving us blind on that aspect, or Airbagman did'know how to use it.However,we have found out that the one piece leak off rail has a valve at the end that opens at 10 bar to provide counter pressure for the injector to operate.We released No.4 leak off and fitted a primer ball with a one way valve and a guage into the rail.When to bar pressure is applied it starts and runs on 3 and bit cylinders(No 4 leak off exposed to atmosphere and no leak off occuring)Rail pressure on start up is 225 bar, rises to303-309 bar.Can only run for about 3 minutes as the leak off pressure gets to 8 bar and one joint we have made blows off.When the fuel systems are dry(factory assembly)how to they get the 10 bar pressure in the rail or is it a fault of all the
hydraulic amplifiers in the injectors ?

Hi Phil,

I'm with Alan, if clip says that there is a problem with the Injectors then thats where you need to start. An Amps clamp or a scope may be your easiest option.

Note; these systems can operate at voltages up to 200 volts !!

The 10 bar back pressure is used to quickly fill the internal chambers in the body of the unit, without this the Injector will not work correctly.

The supplier of your pressure test kit should have an adapter (or four of them) for testing the leak back on this type of system. HTH
