renault master 2.2 dti, 2003, non runner
need your help with the van above, customer brought it in as a non runner, it turns over but won't start.
I have plugged it into diagnostics but found nothing, tested fuel pressure, leak back on injectors, checked all connections from ecu still blank.
customer says it drove fine apart from slight loss of power, no overheating problems or smoke from exhaust, header tank was empty on arrival :~ so could be possibly a head gasket, or maybe water pump or a pipe leaking? no water in oil or visa-versa, timing on inlet side is out probably out by 3 teeth, perhaps i'll try that first, if not what could be the worst possibly diagnosis
Regards
Jim

JimWelcome to the forum. Another flea-bay bargain? The lack of water and the confirmed[?] belt slip suggest something radical has happened mechanically. Done a compression check? Any signs that it's already been apart and reassembled? What's the fuel pressure cranking and do you have rev info showing?

Hello Angus.
he's had it for yrs apparently, no obvious signs that anyones had a go.
he had the cambelt changed last yr so maybe they timed it up wrong? but it's diffinatly out by 2-3 teeth not sure how that's linked to no water in header. what could mechanically go wrong with these engines, what's the common problems?
fuel pressure cranking, 380 bar/5510 psi.
Regards
Jim

2.2 DCI, G9T is this?If so, generally all sorts of problems!!!!! Think you need to start with the basics, get the timing set right, compression / leak down test etc. These absolutely will not start unless they have a good battery and healthy starter motor- 300rpm min at cranking for them to start.
On a knife edge !

Hi.
Call me stupid, but how comes this vehicle doesn't have timing marks for easy adjustment?
I know you have to lock the crankshaft using locking pins, but does it push into a hole in the crank, or does the crank sit against it? i've tried getting it set to TDC but it locks in about 3 different places.

it is unusual for just one cam to jump 3 teeth out are you sure of timing marks??
Also just done one of these for a local garage in a laguna 2.2d, non runner, no stored codes ,they had done a bleed back test all ok so asked me to have a look
Scanned it first no codes in eobd or in Renault fuel pressure was 400 bar on crank but no fire,all readings from live data looked ok so i decided to do a few actuators and after driving the egr valve a couple of times it fired up and was very smoky taped the egr valve smoke cleared and it revved up nicely,so told them to strip /clean or replace the egr and left them too it(minus a few quid for diagnostic testing )
So its defdefinitelyorth doing a check on egr system and then a comp test ,then if still no joy get the correct kit for the timing belt and use carefully these are easy to get wrong-good luck!

Hello.
I'll definatly give the EGR a try.
I have the correct timing kit for the vauxhall/renault, just a bit unsure as to how the crank locking pin fits in, because i can lock the crank at 3 different places, so not sure which is TDC, especially as theres no visable markings on the crank pulley.
The timing marks i see on the camshaft are flat surfaces on both sides, the exhaust side was vertical, the inlet about 3 teeth out.

the correct place for top dead is in front of the block by oil filter housing (from memory)but i know its a real PIG to get at. You can always whip out no 1 injector or glow plug and use a TDC finder or dial guage to confirm tdc (make sure on bottom pulley that the little hole is around 12 o clock)as it is possible to time it up at the wrong tdc-n01 firing or no 4 firing!Then fit both cam tools and both should be vertical!If the timing has jumped on one cam you need to find out why?

how is there a wrong TDC? i thought tdc was when the no1 and no4 pistons were at the top of there stroke all in 360degrees. do you mean BDC then.
i also haven't seen a small hole on the bottom pulley, there's 4 but none of them help.
anyhow thanks, i'll be checking into it in more detail later today, and i think maybe someone as possibly tried a diy job with the cambelt as it's not very old.

what it is is that there is two positions for tdc one with the injector pump firing on no1 and if you turn the engine back round one turn to tdc again the pump then fires on n04 so because there is no timing marks for pump only tdc its vital to make sure that its tdc and firing on no1 !!!!!!AD has all relevant instructions!
