Just returned from a mini tour consisting of visiting Glen Esk, Dunkeld, Dounne, Loch Lomond and Crieff and all was going well, our nearly 30 year old MH had been driving like a dream. We even helped out a fellow MH who had a flat battery in Loch lomond ( Firkin Point ) see pictures. After Leaving Loch Lomond we headed up to Crieff where we decided to stop off at a small CL for the night.

All was good, We left in the morning and got a few hundred yards out of CL and BOOF !!! MH just died on us, conked out wouldn,t start, looked at all the obvious signs, but no She wasn,t starting, She was turning over fast but wouldn,t start, which made me think fuel related, But The gauge said a quarter of a tank of fuel? but it is old so could be dodgy gauge. So of I went walked 3 mile round trip and got fuel and put it in the MH, Tried a few times to start nothing? So bit the bullet and phoned Green Flag, a couple of hours later we were recovered to the nearest Garage, which ironically was only 500 yards away.

The Garage looked over our MH and said possible coil or crank sensor? Anyway the Garage said that they could only source the coil and not the crank sensor and that it would not be here until Tomorrow, but after discussion I told them that I wasn,t prepared to take a 50/50 chance of that being the problem, given that the coil had recently been changed by my local Garage.

So we decided to call Green Flag again and they came and recovered us and took our MH to our local Garage and us home, awaiting outcome of the problem?

Such a shame that your holiday ended this way. As your MH is nearly 30 years old, parts inevitably become harder to source. @Wildbill was collating a list of parts suppliers for older vehicles. We hope it's nothing too serious and that you'll soon be back on the road.

Coil? Is it a petrol engine?
Hi, Yes its 2.0 ltr petrol. It has had new ht leads , plugs, distributor, rotar arm and coil as I was having starting issues with it, since all that was replaced it has being starting first turn and driving like a dream, until the other day:cry:, Will have to wait and see on the outcome?

7 years campers before that
ours died regularly it was fuel tank rusting away internally did they try starting it on squirt to prove it wasnt fuel starvation

I'd be amazes if it had a crank sensor ?

I have been doing some research my self and I am also a member of the RTMR ( Renault Trafic Motorhome Register ) and according to what I have read in some of the forums they do have Crank Sensors, but I am not mechanically minded so will have to wait and see?

You are lucky they recovered you twice for the same issue - ours wouldn't (Caravan Guard)

I actually didn,t think they would without payment, but My Wife complained about the time it took to get to us the first time, ( two and a half hours ) so maybe that came in to play?

Ah maybe - we were recovered to a Dealer who decided they couldn't look at the van so we wanted to go elsewhere - I called Caravan Guard and when told we couldn't use it for the same fault I offered to pay but they told me we were too big (in spite of the fact they took us from the A1 to the dealer). Luckily for us the Dealer we bought it off arranged for a local recovery to a Garage nearby as it was under their warranty.

Try feeding it sum petrol straight in to carb if it fire its not the coil thay it normaly have intermittent fault before any thing happens and I don't think ther would be a crank sensor

Is it fitted with a timing belt or a chain ?? if a belt i hope that has been ruled out.
Best of luck and hope its nothing to big :)

First garage I was recovered to ruled out timing belt, they said no spark , I obviously don,t know the first Garage, but I have every faith in my Local Garage finding the fault and will update when in the know?

Can't really see what a crank sensor would do.... 1990 It won't have an ECU for it to link to.
Only thing on the crankshaft will be timing marks.

For crank sensor read ignition trigger. IIRC the trigger and ignition amplifier are a single module inside the distributor. If there's no spark and the coil is OK the module will have failed. Only very early versions of that engine had points/condenser.

Before I had all the work done ie ht leads , plugs, distributor changed, I assumed given its age that it had points in the distributor, but no its electronic ignition. Also I have said in previous post that the engine is turning over fast, what I should have said is that it is turning over as normal but wont start, I would like to thank everyone for there input/help and I am sure and hopeful that it will be something simple? time will tell.

There isn't anything particularly complex about any part of that engine. Assuming mechanical integrity it needs two things to fire: a spark; and fuel. The first can be seen with a plug removed. If there's a spark then it isn't getting fuel. Final proof of this is a quick shot of starter aerosol down the carb whilst it's spinning. If an engine dies suddenly as though the ignition has been switched off, or fails to fire at all when spun on the starter, the fault is fairly certain to be ignition. My money is on a fault caused by the recent work on the engine. The

Thanks for your input it all helps, but I fail to see why recent work would have any bearing on this? The work which was done in December last year was purely for my peace of mind and to make it as reliable as possible. After the work was carried out it never missed a beat or failed to start. We were having starting issues with it before the work was carried out, ie some days it would start other days it wouldn,t.
The vehicle has got a very good service history , but simple things like ht leads , plugs and distributor had not been changed for a while. Hence why I had them changed and all was good until the other day.

Actually it needs four things to fire, air, fuel, compression and spark.

I'm not casting doubt on the work done, or the person doing it. It is usual to look back at recent work done when considering a fault or failure. I hadn't realised / hadn't read that the work was done as long ago as that.

UPDATE !! MH still not fixed, Garage only just returned after long weekend off. But We are beginning to lose patience with them as they still have not pin pointed the fault? Just to let other people know who may have reading / replying to this post that it does have a Crank Sensor Pulse. As I took it off myself on Sunday and cleaned it but still no start. They are telling me that possible faults are Crank Sensor, Ignition Coil, but after doing more research and help from the Renault Trafic Motorhome Register it could also be the Renix Control Unit? My Wife and I are seriously thinking of finding another Garage, one that who are Mechanics and not Fitters ! but that would mean more costs of getting it recovered. :mad:
