Renault Traffic won't start - was running OK .

[dooroy]

Changed engine in 2005 Renault Traffic 1.9 a few weeks back - alt belt broke and took timing belt with it .
Replacement engine was running fine but after a few days developed a miss at tickover - traced to injector no. 2 which was stuck solid and would not budge .
Owner needed the van so continued to drive it as it was running OK except at idle .
Then one morning having driven about 40 mls problem free he pulled in for diesel .
Van refused to start when he returned to it - and hasn't started since .
Don't have scanner - a friend scanned it earlier but we then discovered it was giving false info e.g saying there was a problem with lambda whaich van didn't have . Having read up on this it appears that this kind on info means scanner is not compatible .Renault appear to be difficult to scan ?
1) Could high pressure pump fail in this way - doesn't have an electric pump ?
2) Could immobiliser do this - engine willl fire for second or two but no go .
3) Can fuel pressure be checked by checking voltage in sensor wire from fuel pressure sensor ?
And just as a matter of interest I fitted a new alternator belt with replacement engine - it was beginning to shred again . Luckily hadn't affected timing belt . And I had checked tensioner etc already .
Persuaded owner to buy a clean 00 Hiace for sale locally as he needed transport - but will have to get Traffic running again .
Any ideas etc greatly appreciated .

get the right info otherwise everyones wasteing their time.
it should be able to read basic codes under eobd.
ive had pumps and injectors go down on vivaro/traffics.
ive had rotten wires/fuses/relays/tdc sensors cause non runners in other reno's.
every job i seem to get seems to be different.
on a common rail its ultra important that the fuel pressure builds up to min or more at crank other wise the injectors wont be commanded to fire.
even a lazy starter can cause this.
get someone over who got a dedicated scanner and can read live data to tell you what is going on,oh and treat what customers say with a pinch of salt,they can be lier's mistaken!!!!

How can it pick up a fault code for lambda if its not compatable whatever that means , and if its 05 it should be eobd unless its been manufactured well before the registration or been messed with.

And you say it's got a bad/knackered injector .... But left it

Have seen phantom codes like this with other cars. My take on it is an anomaly with the scan tool used, not the car itself. Then again, it is a Renault...

Using the scantool dooroy, can you see the basics like a crank signal and rail pressure?

[dooroy]

(a)When the faulty lambda showed up I went ' Googling' (as I had changed the engine and knew it did not have one ) and discovered that the exact same thing had happened to others a number of times with a Renault Traffic - and a Renault 'tech' had answered that this indicated the scan tool was not compatible with Renault vehicles (and it would suggest that all feedback would be suspect ). It also indicated a problem with the glow plugs but they all checked out fine ( 4 in the engine and 4 in the coolant )
(b) The injector would not budge and I was going to send it to an engine reconditioner about 50 mls away . Talked to them and they have succeeded with most of these - but of course the possibility of injector breaking etc had to be kept in mind . The owner was busy and decided to keep going until such time as he could manage without it for a day or two. It was running reasonably well - until it refused to start .
(c) don't know much about scan tools leew - the guy who scanned it has a Delphi scanner for a few years so I leave that to him. Will ask him about crank sensor and rail pressure .Rang a friend who has a Launch and he told me that it didn't always give good results with Renault either . The 2 Renault dlrships which were about 25 mls away in opposite directions from me have both closed down - gone .

Came across a site ( which I'm trying to find again ) which said
1) use a vacuum gauge to check at HP pump inlet when cranking - should give a fig of -0.7 to -1.0. Otherwise pump has failed .
2)sensor wire from sensor on fuel rail should read min of 1V when cranking but seemed to say 2V needed to start .

Thanks for replies . Will keep trying .

My Launch reads these no problem

My Launch reads these no problem

Even snap on gets into renault !

So does a brick through the side window

[dooroy]

Well put welshy - maybe follow the brick with some flammable liquid and match ;D in case problem is caused by dampness .
They ( Launch and Delphi )seem to 'get in ' easy enough - but its what they get out is the problem .
