Remember at auchterarder we used to light fires under the derv tank to thaw out the fuel and other locations but not was funny seeing all the glows from afar
them were the days NOT!
A lot of wagons ended up as scrap when the fires got out of control, we had an Albion with 4 cylinder Gardner knocker and a wood cab, looked rather sad when the fire got out of control, the boss was convinced it was done on purpose 😇😇😇😇😇

If you want to check your immobiliser circuit…. Just cover the fob with tinfoil and try starting the engine…. As the engine spins you will see a flashing light and the engine will not start… your two key fobs are working properly as is your lmmobiliser system… so get out of that rabbit hole and never return…a Diesel engine has to reach a certain RPM before it fires (750?) if it is not… the engine will keep spinning until it does reach the sweet spot provide you keep it on the key…. Us elder lemons have a habit of pumping the accelerator pedal when trying to start a stubborn engine… a big no no on the modern engine because the are controlled by ECUs keep your foot away from the pedal ( tie your foot to the seat pillar)…. Even when on a normal start…the ecu will get pissed of with you changing the parameters all of the time and turn on the money light (engine management light on the dash). I haven’t enough details of the hard start to send you down a rabbit in any one direction. Burn Camino.

I had occasional starting problems with my 1998 Ducato. It turned out to be a bad earth to the chassis. A common fault on many Ducatos and Boxers.
You should disconnect it, clean off all the rust, put a blob of synthetic grease on the nice bare metal and bolt it up again.

My Fiat Ducato based campervan has had intermittent starting problems for years now. The starter motor turns the engine over fine but it sometimes just won't start however many times you try! There seems to be no pattern to these problems. Sometimes it won't start from cold, other times it won't start from hot. My local garage has done the electrical fault finding analysis on numerous occasions and say they don't know what's wrong with it.

It is a 2008 Ducato with the 100 Multijet 2198 cc engine. It's the one with the chain driven camshaft.

Has anyone experienced this problem on a van of this type and if so did they manage to cure the problem and what type of repair was needed?
Could be diesel jets.

Hi. Diesel jets problems always stick around and when the scale flips bad you’ll get a diesel knock (the knock is as loud as a big end knock and sometimes confused with one)… no wrong rabbit hole.
Buen Camino.

Nothing of that kind. All lights are as normal when the van won't start. However the idea that it might be something to do with the engine immobiliser is interesting.
What I wrote here was true to the best of my knowledge when I wrote it. However on closer inspection of the lights on the dashboard I have realised that the normal sequence when you turn on the ignition is for the immobiliser light (a little orange padlock symbol) to flash once and then go out. If this does not happen and the light stays on, then when you turn the engine over the van won't start. To rectify the problem all you have to do is turn the ignition off and back on once or twice and it reverts to the normal sequence of the immobiliser light flashing once and then going out. When the correct sequence has occurred the van always starts first time. I am absolutely kicking myself that I have not spotted this before. I'm also concerned that my local garage didn't spot it when I asked them to look into the intermittent non starting on at least two occasions. I guess there must be a glitch in the immobiliser software which is causing this and no doubt a Fiat Professional dealer could re-programme the system to eliminate the glitch however I don't think I'll bother with having that done. Many thanks to all of you who contributed to this thread.

Still think you should get the keys reprogrammed imho and rotate the use of keys so the bsi /ecu recognise the keys

Hi Roger, glad to your sorted. 90% of problems blamed on the ECU are wrong.
It is worth keeping the spare chipped key handy for the next time the duke does it.
Put the spare key in and if it starts, then it’s
Worth having a look at the chip (in correct position in the fob) in the working key.
If it doesn’t start (light says on) then it’s worth looking at the antenna ring (the ring hasn’t moved out of position) around the ignition barrel. Also keep in the back of your mind about signal interference
( automatic gate systems, masts, fuel pumps at petrol station, etc. Just have a look round with in about 100 feet or so to see is there anything electrical to interfere with the immobiliser and never have another chipped key on the same key ring.

I had the same problem with my Fiat. In the end it would not start at all. Fiat commercial dealers in Gloucester found the problem.....
A short in the aftermarket Sigma alarm wiring ... I never ever used the alarm, not even to see if or how it worked but it caused my problems.
