Starting a diesel

These things don't always work quite as you expect.
I tried to start a petrol engine a few weeks ago which had a fuelling problem that I hadn't got around to fixing so I always had to sprinkle a little petrol into the intake which was downdraught so simple. Anyway, before I found the petrol can I found an aerosol can of carb cleaner which is some kind of solvent so I thought I'd use that instead. No chance .... zero ignition. A splash of petrol and we were away.

I would suggest a stop cock in the fuel feed as these are notorious for leaking ... they are supposed to be a 'heat activated' valve in the body - but I know mine does not close.
I would also advise a separate fuel feed from a small medicine or pill container .....
I had a connection to fuel system when engine was changed ... I lost my old small reservior .... it was trouble because the glow plug feed did not shut off fully ...
I reverted to a separate small supply and all was good again.

New boy on here and diesel does not really bother me as have a Hurley 18 with outboard but it has always something I have not fully understood.
When a guest on other peoples boats, some start on the button, others need to have some heat device. From my personal experience I used to have a Tranny van that would always instantly start by turning the key, after changing to Peugeot I had to wait for the light to go out before it would even think about starting.
Question is, why?
Surely a diesel is a diesel is a diesel.

As regards using aerosols to start an engine (not including Easy Start) it was the propellant that did the work, not the spray., many now use a non flammable propellant.
"(CFCs) were once often used as propellants,[18] but since the Montreal Protocol came into force in 1989, they have been replaced in nearly every country due to the negative effects CFCs have on Earth's ozone layer. The most common replacements of CFCs are mixtures of volatile hydrocarbons, typically propane, n-butane and isobutane. Dimethyl ether (DME) and methyl ethyl ether are also used. All these have the disadvantage of being flammable. Nitrous oxide and carbon dioxide are also used as propellants to deliver foodstuffs (for example, whipped cream and cooking spray). Medicinal aerosols such as asthma inhalers use hydrofluoroalkanes (HFA): either HFA 134a (1,1,1,2,-tetrafluoroethane) or HFA 227 (1,1,1,2,3,3,3-heptafluoropropane) or combinations of the two. More recently, liquid Hydrofluoroolefin (HFO) propellants have become more widely adopted in aerosol systems due to their relatively low vapor pressure, low global warming potential (GWP), and non flammability "

You still haven't told why fitting a thermostat helps start a diesel. I am intrigued.

ThermostaRt - It puzzled me for a moment too.

I'm envious of people with self bleeding diesels. Mine is hell on earth to bleed, often taking a few attempts. Enough to put one right off changing fuel filters for the above reason.

I fitted a 'bulb' fuel 'thingy' in line which appears to have negated the need for bleeding.
My Ruggerini also says to have the throttle wide open for cold starting, which alarmed me so much that I couldn't do it so did 1/2 throttle and a shot of Easy Start.
Gotta get me the Rotrax tin though!!

My lift pump is perfectly adequate for pumping the fuel through. It's the bleeding the fuel filters, then two points on the injector pump, then cracking off the injector pipe and after all that it still won't start and so begins the whole sequence again ?

Did you tickle it? I've heard recently that this is required.

Tickle it? I've wined and dined the dam thing and it still doesn't like me messing with its fuel supply ?
The manual states never tow start or crank to pump fuel through as this can damage injector pump..

Never had a leak on any of mine and no separate reservoir is required, that was a very old system that was found to be unnecessary.

The Thermostart produces a flame that is drawn into the cylinders providing heat exactly where it is needed. Far more efficient than heater plugs.

I'll try reading the posts correctly in future - thermostart not thermostat!

Fair enough ... I know many have the feed from there ... but I'm just a cautious fellow having tried it and then had all sorts of fuel supply problems and the Thermostart not closing of fully. My feed needed modifying to do it ...
For someone thinking of adding it to an engine that has not got the fittings already ... I would think that keeping it simple and only ONE fitting - that is into the air intake would be prudent. Why tap into fuel line and run risk of creating a problem ?
Small container of diesel clipped above it ... simple... or as I have ... a stiff piece of tube vertical of the fuel nipple that holds about an egg cup full.

Bedford ? All Bedford TK's ... TM's I rode in had Cold Start levers - that basically bypassed the governor on the pumps and allowed larger volume of diesel to be injected ... no glow plugs or thermo's.
In fact Leyland Bedford ended up removing the pull lever from the cab and putting it outside under the rear of the cab same as Fords ... to stop drivers pulling it out to get up hills !!!

I'm very interested in this, having a VP2001 that is often extremely slow to start when cold (using the approved cold start procedure) but fires instantly when warm. Is the Amazon item linked to earlier all that's required, or is that just a component to go into a thermostat setup? I couldn't see quite how it was to be connected...
Alternatively, any other links to a gadget that would do the trick would be very welcome!

Bedford 466 and 500 both had thermostarts.
