Quick question,

I have got a little to adventurous with my merc, I was running it on WVO but I think I have used too much maybe 90%.

Its now not starting.

What is the quickest way of getting some diesel into the IP (fuel pump)

The tank is very low so I just need to get it to the garage and get some diesel in.

Many thanks in advance.

Regards
Brett

Well, sir, before this discussion progresses any further, I advise you to suit up, cause it can get pretty hot.

Anyway, hopefully assuming nothing is too far gone, your best option would be to disconnect the fuel supply line at the lift pump and run it to an external tank (anything will do, a clean milk jug) full of petro-diesel, then take a hair dryer at the warmest time of the day and heat up the injection pump as best you can, give it a few full glow cycles, fully depress the accelerator and start cranking. Once it starts firing, refill the regular tank with petro-diesel, reconnect the supply line, prime it, and hope for the best.

If you are interested in using bio-fuels, I advise you to do quite a bit of reading before experimenting.

Thanks for your response. Well I have been running cars on swo/wvo for about 6 years and have experienced some problems and usually got over them and learnt what mix of WVO/Diesel to use on which car. I have probably only done about 30k on wvo so hoping no real damage.

I was actually using WVO with about 10% petrol in.

When you say use "petro-diesel" are you talking about starting it on a petrol diesel mix?, also its not really that cold here.

Can't say what kind of damage you'd have with 30k with a blend. The two-tank system is usually the only way of running VO that can get respect around these parts. Blending seems to be hit or miss, some people can run it fine, and it can trash other peoples engines.

I use the term "petro-diesel" to avoid confusion with bio-diesel. Probably unnecessary. Just straight ULSD. Still try to get the oil as hot as you can.

wonder if we use 2 T connector to join the in/out line so the out line's warmed diesel will get into the in line.
The return line's dsl suppose to have cooled the injector, 90% of them get back into the tank as I was told.

Umm not good.

Syphoned all the oil out of the fuel filter housing and filled with neat diesel, then connected a bottle of diesel straight into the lift pump. Pumped the primer a few times and the diesel was sucking into the fuel filter. Tried starting 4-5 times and nothing not even a splutter.

The thing is the car didn't breakdown, it was running OK. I just went to start it a few hours after my last journey and nothing.

Any more ideas for things to check?

JUST REALISED SOMETHING 30K, I MEANT 30 KILOMETERS ABOUT 20 MILES

Alright, so this is just a basic no start situation. 20 miles will not have caused any damage, although I'd still advise only using petro-diesel until you diagnose and fix the problem.

First thing to check are your glow plugs. Check resistance. Then try cracking the injector lines to make sure you don't have any air in the lines which may have happened when you ran the tank down.

Yep,

I sprayed a bit of easy start in and it started ok run it around the block a few times and goes ok, stopped and started ok. Left it for an hour no start.

Has to be glow plugs.

Time to change and possibly upgrade from the older loop style glow plugs.

Thanks for your help. Anyone here upgraded?
