White cloudy fuel

[duffdef]

I've replaced the engine in a discovery I bought, Having difficulty starting it/ running it. I've replaced the head gasket and had it skimmed etc, I've bled the fuel system all the way to the injectors and all the timing is spot on. My concern is The fuel in this disco is white and cloudy at the injectors, it doesn't smell of diesel and certainly doesn't look like it either. The guy was running this on cooking oil for a few years and I'm wondering as it's stood for a while has the cooking oil gone off "so to speak" thus making it difficult to run/ start.

Any info would be much appreciated thanks

I think it would be a good idea to drain the fuel system completely and full it up with fresh diesel. A flush through with a gallon or two of fresh would also not come amiss. I would undo the fuel hose unions to do this and flush right up to the fuel filter.

Then I would:

1. Clean out the sedimenter
   
2. Replace the fuel filter, refilling the filter with fresh fuel also
   
3. Put a good dose of REDEX or some similar cleaning compound in
   
4. Give it a good run out on the motorway for 20-30 miles
   

That ought to give the system a good flush out. You may want to replace the fuel filter again in a couple of thousand miles just to be sure.

Thank you for the info, I soaked a clean rag in the fuel from the injector pipes and i could not get it to burn no matter how hard i tried, I'll do a full flush of the fuel system and do the pointers you mentioned too, Thanks

the white cloudy stuff sounds like vege oil that has absorbed water...
